Purge “Registered Applications” to Speed Up AutoCAD
Comments(5)Matt Murphy showed this tip in a class at Autodesk University. He explained that AutoCAD attaches XData to objects in drawings and this data allows information to be associated with specific objects. The problem is that when objects that contained XData are deleted from the drawing, the registered application becomes unreferenced. If you get a large amount of unreferenced registered applications in a file, it can increase the file size and cause sluggish performance.
The only way to purge these unreferenced registered applications is to access the Purge tool from the command line. Type -PURGE on the command line and you will see this:
Enter type of unused objects to purge [Blocks/Dimstyles/LAyers/LTypes/MAterials/Plotstyles/SHapes/textSTyles/Mlinestyl es/Tablestyles/Visualstyles/Regapps/All]:
Then type R (for “Regapps”) and it will prompt you with this:
Enter name(s) to purge <*>:
Type an asterisk (*) to purge them all. It will then ask you if you want to verify each registered application name to be purged. I recommend typing N to speed up the process.
That’s the hard way to do it if you have lots of files. Check out this app from Autodesk for the lazy way.

Let me know if you have any questions on this.
I have access to the guy who wrote it ;)

Thank you Tom and Christopher for sharing these links.
You might want to tell people that the app only works on 2008 and 2009.
Hi Guys,
My Auto Cad 2008 is making my PC very Slow when I’m working on a CAD file. Could please help me to increase the performance?
