SmartPurger - Script for AutoCAD

About | Download | System requirements | Purchase
Documentation | Revision history | License agreement | Customers


SmartPurger is a batch and script utility for processing multiple AutoCAD drawings with full control. Execute LSP or SCR files on multiple drawings. SmartPurger handles crashes so the AutoCAD batch processing continues to the end and leaves bad drawings to be corrected manually. Many purge and cleanup settings available. Useful before backups and distribution of drawings. The file's modified time stamp can be restored.

The free trial without license file is fully functional except that you can only batch process 10 drawings per session to give you the chance to confirm that the program works as expected. When you purchase you can use SmartPurger with no limitations.

Batch process drawing files with SmartPurger to avoid bloating or corrupt files by running AUDIT and PURGE on them or any other custom command you want.

SmartPurger batch processing for AutoCAD is useful if you want to minimize the size of files before a backup or before sending drawings by e-mail, burning to CD or just to use as a quick viewer of drawings. You have options to save the files to a separate folder or to a different drawing version.

SmartPurger can execute custom script files (.SCR) or AutoLISP files (.LSP, .FAS or .VLX). We can help you create them based on your special needs.

SmartPurger can make use of AutoCAD Core Console that was introduced in AutoCAD 2013 making the scripting process faster then ever as the Core Console takes less than a second to open per drawing. In a test using the Core Console took 11 minutes compared to normal AutoCAD 2013 that took 58 minutes to process 145 drawings.

You can set up SmartPurger to run different AutoCAD applications for different drawing file versions. Optionally specify the profile to be used when starting AutoCAD.

From a real project: 1773 drawings and a total size of 526MB in 2000 DWG format become 218MB in 2004 DWG format. Conversion and purging was made totally unattended. SmartPurger can without problem process 10,000 drawings and more.

You can run audit, zoom extents, create preview icons. Convert between versions. Purge Blocks, Detail view styles, Dimension styles, Layers, Linetypes, Materials, Mline styles, Multileader styles, Plot styles, Regapps, Section view styles, Shapes, Text styles, Table styles, Visual styles, Page Setups, Filter states, Layer states, Layer manager states (Express Tools), Line objects without length, Text objects without text, embedded VBA code, registered applications collections, Anonymous Groups, Groups, Orphaned Data. It's possible to restore the date and time of the file to what it was before the scripting. Delete .BAK and other temporary or garbage files. And much more.

Remember that this is a very powerful tool and make sure you understand and know what you do when you use it. Read the documentation before you run it. Try on some test files/folders as a start. To be on the safe side make sure you have backups before you run.

If AutoCAD's -PURGE command crashes AutoCAD because it runs out of memory (FATAL ERROR: Out of memory - shutting down) when purging Regapps make sure to use the purge option "Purge all registered applications collection" instead. It can take really long time (from some minutes to some hours) so set the timeout to max value (100000) and leave it running during the night. Sometimes it can help to unload the xrefs on all drawings you want to purge from Regapps otherwise they just keeps coming back. Create a small lsp file with this code and run it first on all drawings.
(command "._-xref" "_u" "*")
After that you can run the files, purging the Regapps. Remember that all nested xrefs has to be run.
Then run a lsp file that loads the xrefs again using code like this:
(command "._-xref" "_r" "*")

Since release 2.6 you can use the option "Purge Regapps using ASDKCleanRegAppARX.arx (2004-2008)". Thanks to James Maeding that provided it and the ADN team that created it. This is much better than the other options "Purge all Regapps" and "Purge all registered applications collection". Layer filters too are purged with this option.

Quick Introduction | Adding drawings | Run | Drawing list | Right click menu | Options>Settings | General tab | Purge tab | SaveAs tab | Delete tab | Shortcut tab | Variables | Application menu | Tips & Tricks | Known issues

Quick Introduction

Install SmartPurger using any of the downloads.

Alt. 1. Using setup. Run either the exe or msi in the zip file. Default installation path is C:\Program Files\JTB World\SmartPurger.

Alt. 2. Unzip the portable download. Extract the files to any folder on your computer or USB memory and run SmartPurger.exe. AppShortcuts.vbs can be used to create either a Desktop or Start Menu shortcut for the program.

Alt. 3. AutoCAD app. Only for AutoCAD 2012 and verticals or newer versions. These are supporting the autoloader. Installation can be done both while AutoCAD is running or not running.
Enter the below path in Windows Explorer address field and press enter.
Extract the JTBW-SmartPurger.bundle<version>.zip file in that folder. It can look like this where jtb is an example of the user name.
C:\Users\jtb\AppData\Roaming\Autodesk\ApplicationPlugins\JTBW-SmartPurger.bundle\PackageContents.xml should be found in the SmartPurger.bundle folder.
To uninstall, delete the JTBW-SmartPurger.bundle folder.

If you have the license file SmartPurgerLicense.txt place it in the installation folder where SmartPurger.exe is located. For the AutoCAD app the location is \JTBW-SmartPurger.bundle\Contents\Win32 and \JTBW-SmartPurger.bundle\Contents\Win64.

If you have purchase the app you can copy the license file from the above location so you can use it with the traditional installer or portable download.

Start with Options>Settings and configure SmartPurger to work the way you want it.


Select drawings to process.

Click on run.

For deployment on multiple machines silent/automated installation can be done:
For Vista/W7: MsiExec.exe /qb /i SSMPropEditorSetup.msi
For XP: MsiExec.exe /qn /i SSMPropEditorSetup.msi
Use MsiExec in a BAT, CMD, VBS so that the license file also is included with the installation.

Adding drawings

There are four methods to add drawings to SmartPurger.

1. Drag and drop files and/or folders from Windows Explorer. If folders are selected you’ll get a question if you want to include folders and subfolders.

2. Add Folders Only - This adds only a folder. The files are added to the drawing list when you start the script. This one should primarily be used when you want to script really many files. This one give you also the option to delete several files in all folders found, the file types that are deleted are specified in the settings menu.

3. Add Folders - This is to add all the drawing files within a folder or driver. It works recursively.

4. Add Drawings - This is to add drawing files to the list.


Click on Run to start the processing and click on Stop to halt it.

Use the timer to start the script at a specified time.

Drawing list

Filename - DWG or DXF file name.

Path - Path for the drawing.

Version - File version: 2013, 2010, 2007, 2004, 2000, 14, 13, 11/12, 10, 9, 2.6, 2.5 or ??? if the version is not recognized. If it's a folder it shows FOLDER.

Status - OK, Skipped, Access Denied, ReadOnly, Timeouted, "Error: Could not open file" or Skip for files not to be scripted. Educational drawings can be in some AutoCAD versions be detected if AutoCAD is run in normal mode (not core console) and close popups automatically is being used (Best tool to identify educational drawings is EduFinder). The status "Error: Could not open file" might indicate that the drawing has to be recovered. Timeout can happen if digital signatures are attached to the drawing or if the purge process takes longer than the timeout limit.

Size before - size in kb.

Size after - size in kb.

Date before - modified time stamp for the file before the drawing is scripted.

Date after - modified time stamp for the file after the drawing is scripted.

Right click menu in the drawing list view

Remove - Remove selected drawing from the list view

Reset Status - Reset the status for selected drawing

Set Status to Skip - Set the status for selected drawings to "Skip"

Select All - Select all drawings

Deselect All - Deselect all drawings

File Properties - Open Windows File Properties for the selected drawing

Explore - Open Windows Explorer at the folder location of the selected drawing

Start AutoCAD - Start the selected drawing with AutoCAD


The settings are saved in the registry, so you don’t have to change them again the next time you run SmartPurger.

Restore button – Restores the settings to the default settings. This also includes the windows settings for the main SmartPurger window and the column widths and positions of the listview.

General tab

AutoCAD application:
This combo box lists all installed AutoCAD applications. The default value is the application that is associated for the moment to the DWG-files. If you change the application it will also re-associate the DWG-files and use this application with SmartPurger.

This combo box lists the active profile for the active AutoCAD application. And if you want to change it select another one to be used by SmartPurger.

Alternatively specify the path to the executable and if AutoLISP is supported by the CAD application or not. From AutoCAD 2013 and newer the AutoCAD Core Console can be used and will make scripting much faster. Browse for accoreconsole.exe that is found in the main installation folder where acad.exe also is located.

Include DXF files:
This filter makes it possible to also run DXF files. Some non standard formatted DXF's are not version identified but might be run anyway. The version is set to "DXF?". Until anyone wants it (just contact us) the DXF are saved to the closest matched DWG version. 

Close Popups Automatically:
Dialog boxes are closed automatically making it possible to proceed with the scripting process uninterrupted. Click on the button to open the log file.

Include subfolders:
Works with the icon for adding folders and makes it possible to include subfolders in the file search.

Include files with Archive file attribute:
By having this one not selected the number of files can be drastically reduced if done before a backup. This way if you regularly use SmartPurger it might be a good choice. But remember to have it selected the first time you run to include all files.

Add drawing version to the list:
If you chose to have this checked it will take a longer time as each file needs more time to process. But if you select a drawing in the list the version is always showed.

Script timeout per drawing (seconds):
Timeout for processing each drawing can be set. This makes it possible to let the scripting continue if something goes wrong with any of the drawings in the list. If you have large drawings or it takes long time to purge them you might want to increase this value. If the drawing is not finished purged within the timeout limit AutoCAD will be shut down and the next drawing purged.

Run Audit on all drawings:
Run Audit on all drawings to ensure the quality of them. It is the standard AutoCAD command Audit that is run.

Zoom extents Force:
Many likes to zoom the drawings to extents before saving. And it's possible by selecting this checkbox.

PSPACE to avoid zoom extents in a viewport:
If you zoom extents in paperspace and have a viewport in modelspace you might loose your zoom settings if the viewport is not locked. This can be avoided by this option.

Run with SmartPurger on top of other applications:
This explains itself I hope.

Thumbnail Color button can be used to change the background color for the drawing thumbnail that shows when a drawing is selected in the drawing list.

Script/lisp file:
A script file can be loaded and executed as the last thing SmartPurger does before saving and quitting. Since a AutoCAD is started with a script by SmartPurger the main script will be stopped by the custom script that you have added. Therefore you have to add for example QSAVE and QUIT at the end of your script file. The functionality in SmartPurger to save the file to a specific version is lost if script files are used. AutoCAD LT only supports script files. Script files has the SCR extension.

Full/vanilla AutoCAD supports LISP files (extension LSP, FAS or VLX). The lisp file will be loaded just before SmartPurger saves the drawing.

Purge tab

Always know what you do when you purge drawings. If you are not sure make sure to take backups of drawings before.

The Purge options in the left column are standard AutoCAD commands that are run using the -PURGE command.

Number of times to purge:
Enter a number between 0 and 5 for the number of times you want to purge each drawing. This is to allow for purging nested objects.

Purge All
Purge all Blocks
Purge all Detail view styles (Works only for AutoCAD 2013 with verticals or later)
Purge all Dimension styles
Purge all Layers
Purge all Linetypes
Purge all Materials (Works only for AutoCAD 2007 with verticals or later)
Purge all Mline styles
Purge all Multileader styles (Works only for AutoCAD 2008 with verticals or later)
Purge all Plot styles
Purge all Regapps (Works only for AutoCAD 2005 with verticals or later)
Purge all Section view styles (Works only for AutoCAD 2013 with verticals or later)
Purge all Shapes
Purge all Table styles (Works only for AutoCAD 2005 with verticals or later)
Purge all Text styles
Purge all Visual styles (Works only for AutoCAD 2007 with verticals or later)
Purge all Orphaned Data (Works only for AutoCAD 2015 with verticals or later). Orphaned Data is linetype remains from Bentley MicroStation DGN files.

The following options will only be used if AutoCAD 2000+ is used or any of its verticals.

Delete all Page Setups
Delete all Filter states
Delete all Layer states
Delete all Layer manager states (Express Tools)
Delete all Line objects without length (Works with AutoCAD LT 2010 or newer too)
Delete all Text objects without text (Works with AutoCAD LT 2010 or newer too)
Delete all embedded VBA code (WARNING)

Be very careful when using this settings because some applications using the drawing might malfunction.

DWG files can have embedded VBA (Visual Basic for Applications) code and is deleted using this option.

Purge all registered applications collection (WARNING)

Be extremely careful when using this settings because some applications using the drawing might malfunction.

Applications made by Autodesk or 3:rd party developers might create registered application collections. Much of the intelligence of many objects will be lost.

Extended data is grouped by registered application name. Registered application names correspond to APPID symbol table entries. An application can use as many APPID names as needed. APPID names are permanent, although they can be purged if they aren't currently used in the drawing.

Make sure to take backups of drawings before using this option.

Purge all Anonymous Groups
Purge all Groups (This includes anonymous groups.)
Purge all named object dictionaries (WARNING)

Be extremely careful when using this settings because some applications using the drawing might malfunction.

Applications made by Autodesk or 3:rd party developers might create named object dictionaries. For example this will mess with drawings made in ADT. ADT styles, display configurations and a lot more will be deleted even if they are used! Much of the intelligence of many objects will be lost.

Embedded VBA code will also be deleted using this option. NOD: ACAD_VBA

This will remove references that holds materials attached by AutoCAD Color Index used by RMAT even if it's used. NOD: AVE_ACITABLE

AutoCAD 2005 features like table styles will be purged. A drawing's relation to a Sheet Set will be removed.

Even images in the drawings will be destroyed!!!

Make sure to take backups of drawings before using this option.

Purge Regapps using ASDKCleanRegAppARX.arx (2004-2008)

Be extremely careful when using this settings because some applications using the drawing might malfunction.

Applications made by Autodesk or 3:rd party developers might create registered application collections. Much of the intelligence of many objects can be lost.

Make sure to take backups of drawings before using this option.

Extended data is grouped by registered application name. Registered application names correspond to APPID symbol table entries. An application can use as many APPID names as needed. APPID names are permanent, although they can be purged if they aren't currently used in the drawing.

Does not work with AutoCAD 2010 and newer.

SaveAs tab

Create backup files for each save
If checked ISAVEBAK is set to 1 when the script is run. It is restored after the script is ended. If SmartPurger crashes you might have to restore this setting manually.

Restore date and time
This option makes it possible to restore the date and time of the file to what it was before the scripting.

Convert R12 or older, R13, R14, 2000, 2004, 2007, 2010, 2013
The following options are available

"Don't convert format" : If the file is R12 or older and you run AutoCAD r14 the file is saved as R12 format. But if you run AutoCAD 2000 or newer it cannot save to R12 so it saves to R13 format instead.
"AutoCAD R2013 DWG" : Files are saved in 2013 format.
"AutoCAD R2010 DWG" : Files are saved in 2010 format.
"AutoCAD R2007 DWG" : Files are saved in 2007 format.
"AutoCAD R2004 DWG" : Files are saved in 2004 format.
"AutoCAD R2000 DWG" : Files are saved in 2000 format.
"AutoCAD R14/LT98/LT97 DWG" : Files are saved in R14 format.
"AutoCAD R13/LT95 DWG" : Files are saved in R13 format.
"AutoCAD R12/LT2 DWG" : This option is only possible if you run AutoCAD r14. Otherwise the file is saved in R13 format.
"Don't save" : This option makes it possible to chose not to script files of a certain version.

Overrides general setting if selected:
Select first an AutoCAD application, then you have the option to chose a profile.

It can be used if you want for example AutoCAD r14 to run R14-files and ADT 3.3 to run 2000-files.

Save to this folder:
Check the box if you want the drawings to be saved into the folder in the box to the right. If not checked the drawing is saved over the existing drawing. To get a folder click on the button with three dots or just enter the path manually.

Delete tab

Delete only files older than [10] days
Specify number of days. Could be set to 0 to even delete today's files. The following extensions can be searched and deleted at the beginning of the scripting. Observe that you have to use "Add Folders Only" to use this option since it will only search in the folders and the subfolders added this way.

*.BAK – If checked the AutoCAD Backup Drawings are deleted before scripting.

*.BK? – If checked the AutoCAD Backup Drawings (like BK1, BK2) are deleted before scripting.

*.SV$ – If checked the AutoCAD Autosave Drawings are deleted before scripting.

*.$$$ – If checked the AutoCAD Emergency Backup Drawings are deleted before scripting.

*.AC$ – If checked the AutoCAD Temporary Files are deleted before scripting.

*.DMP – If checked the AutoCAD Error Dump Files are deleted before scripting.

*.ERR – If checked the AutoCAD Error Files are deleted before scripting.

*.XLG – If checked the AutoCAD XREF Log Files are deleted before scripting.

*.DWL - If checked the this lock file is deleted before scripting.

*.DWK - If checked the this lock file is deleted before scripting.

PLOT.LOG - If checked the this plot log file is deleted before scripting.


These are system variables that are used by AutoCAD but can be controlled using SmartPurger.

AutoCAD LT is not supported for this.

Controls whether layer and spatial indexes are created and saved in drawing files.
Saved in each drawing by AutoCAD.

Don't change
0 - No indexes are created
1 - Layer index is created
2 - Spatial index is created
3 - Layer and spatial indexes are created

Without indexes will make the smallest files but the performance can be ten-fold if the indexes are used depending on the drawings and how they are used.

Determines the amount of wasted space tolerated in a drawing file. The value of ISAVEPERCENT is an integer between 0 and 100. The default value of 50 means that the estimate of wasted space within the file does not exceed 50 percent of the total file size. Wasted space is eliminated by periodic full saves. When the estimate exceeds 50 percent, the next save will be a full save. This resets the wasted space estimate to 0. If ISAVEPERCENT is set to 0, every save is a full save.
Saved in the registry by AutoCAD.

Don't change

For optimal size set ISAVEPERCENT=0

Specifies whether images of proxy objects are saved in the drawing.
Saved in each drawing by AutoCAD.

Don't change
0 - Does not save image with the drawing; a bounding box is displayed instead
1 - Saves image with the drawing

Having PROXYGRAPHICS=1 will make some files much larger then having it set to 0. ADT drawings are one example of drawings that will be very large having it set to 1.

Controls whether BMP preview images are saved with the drawing.
Saved in the registry by AutoCAD.

Don't change
0 - No preview image is created
1 - Preview image created

The Preview image is adding some kb to the drawing size.

Tips & Tricks

The first time you run SmartPurger it's recommended that you only try a few drawings to see it works in your environment. Use also the feature to save the purged drawing to an alternate folder.

Observe that the first time you run SmartPurger you should go to the Options>Settings and change the values as you want them.

SmartPurger can make use of AutoCAD Core Console that was introduced in AutoCAD 2013 making the scripting process faster then ever as the Core Console takes less than a second to open per drawing. In a test using the Core Console took 11 minutes compared to normal AutoCAD 2013 that took 58 minutes to process 145 drawings.

By preparing a special AutoCAD profile and run SmartPurger with that one. That profile might not load as many menus as the one you usually have. For example if you have AutoCAD Architecture, makes a profile that doesn't load ACA menus.

You can save older drawings to another format. This is useful if the drawings are missing the preview icon. Purging is optional.

To sort the list click on one of the column headers in the file list. If you click on the header a second time it changes from ascending to descending.

Resizing of the column is possible by dragging between two column headers.

You can drag on the column header to move a column.

To select more than one file in the file list use Shift or Ctrl.

To select all files in the file list press Ctrl+A.

Files that are read only or opened and locked by any AutoCAD session are not processed.

Really corrupted files are not processed, they are skipped.

If SmartPurger is minimized AutoCAD will also run minimized. But notice that this disables the automatic closing of some dialog boxes that might result in a timeout.

If you want to filter out what drawings to run you can use the search function in Explorer and then drag and drop the drawings into SmartPurger.

Why does SmartPurger not make the drawings smaller? A 4kB drawing is now 26 kB! That could be because the old file was in another version and or it didn't contain the preview picture. Otherwise you might notice that a file of 100kB goes down to 75kB or something else depending on how well it was purged before.

The BAK files are not deleted even if I selected the settings on the Delete tab to delete BAK files. The deletion happens before any DWG's are processed and if the setting on the tab SaveAs is set for "Create backup files for each save" a new BAK file will be created.

Have you got any of these pop up message when opening a drawing?

This application has detected a mixed version of AEC objects
participating in this operation.

Newer AEC objects will be dissalowed from participating in this operation


This application has detected objects from a newer version
in this drawing.

Some commands will not be available.

Save this drawing from the original application as AutoCAD 2000 format
either with AEC objects exploded, or with ProxyGraphics turned on,
and attach it as an Xref in order to use it as a background.


ARX ERROR: eDuplicateKey

This might be because you have used ADT 2004 when working on the drawing. If this was unintentional you can remove references that triggers this by using the "Purge all named object dictionaries" option. But be aware that this might make the drawing malfunctioning. Use with caution.

Information about the older version 2.8:

SmartPurger 2.8 documentation can be found in the SmartPurger Help file.  If for some reason the file will not open at all, right-click
the .chm file, click Properties, and then click Unblock (this button is on the general tab). You might also need to save it to your hard disk to have it working.

Version 2.8 installation tips:

Installation on Windows Vista requirements that might be needed: Disable User Account Control (UAC). Restart the computer. Download and install Msvbvm50.exe from Right click on Msvbvm50.exe and select Run as Administrator, after that right click on SmartPurger setup.exe and select Run as Administrator. Enable UAC.

If you run into getting a dialog box saying "Run-time error '339': Component 'acThumb.ocx' or one of its dependencies not correctly registered: a file is missing or invalid" see this blog post for a solution.

Vault tips:

Check out a folder to Work Space.
Run SmartPurger on the files.
Check folder back into vault.

Known issues

Partial opened and saved drawings might cause timeout as some commands like PURGE are not allowed.

Purge Regapps using ASDKCleanRegAppARX.arx (2004-2008) should only be used if you have AutoCAD 2004 up to AutoCAD 2008.

If SmartPurger hangs with AutoCAD running and the drawings gets timeouted the reason can be that you have some of the palettes opened automatically. It might look like this on the command line:
Command: _ToolPalettes
Command: _aecprojectbrowserstartup

Try to make sure these are not opened automatically.

1. Click Tools menu within AutoCAD > Options.
2. In the Options dialog box, click the AEC Project Default tabs.
3. Select to not show the Project Browser at Startup

What customers have said about SmartPurger

"this program is one of the best utilities I have seen in a long time ... I just purchased a copy yesterday and ran it on my network today cleaning up a few larger projects. Some drawings went to 10 % of their original size - finally a tool that can get rid of all that useless invisible data in the Architect's drawings. This will free up a lot of space on my server ...

Thanks for doing a great job and making it available for an affordable price !"

"I have run this on your 200gb of AutoCAD 14-2005 DWGs and it is an awesome tool, we have gone down to only 125gb! That's saving us hours and hours of backup time." - PB

"First I wanted to thank you, Smart Purge is a mini miracle, we have several hundred gigabyte of CAD files, dating from 1992 to 2007 and have used Smart Purge exclusively to convert, clean, and repair ALL of our files in readiness for the 2008 release of AutoCAD, as before now we would open, and save as needed, Audit and Purge files as we went along, and generally waste 100’s of man hours trying to remove native AutoCAD issues like bad layer, and random object data corruption we considered Smart Purge a absolute life saver." - PB

"è un programma fantastico !!!!!" - arri

"Thank you so much for your quick response ... much appreciated. I have been using the SmartPurger quite a lot over the last few weeks and literally freed up several Gigabytes of space on my server. I noticed that the new version allows to run a custom script - you must be a mind reader ... I was hoping for that possibility to be added for a while and was not aware it was already included until I looked at it last evening as I had to re-install." - Herbert

"Helpful utility programs are always great and worth the money in a business where time is money. SmartPurger is one of the best values yet!!" - John

“SmartPurger from JTB World helped me clean up and reduce the size of 100's of files from our architects. Many were DWG files converted from DGN and contained a lot of Regapp IDs and other artifacts. I am delighted with its read version number feature, which I use regularly to check that I am sending the correct version of DWG, when I am sending a large number of files to co-consultants who work in lower releases of AutoCAD.”
Plessey Mathews, Architect

“SmartPurger from JTB World is the fastest and most versatile batch and scripting utility I have ever used. It is also high in cool factor!”
