What's the difference between "purge" and "-purge"?

[danielmiller19929945]

We use both of them...we use purge first, then -purge, and -purge erases up to 30,000 or so more unused applications. (when we do -purge then "r" for registered applications.

Will that erase AEC files, or shape files...or maybe anything we actually need from those files?

Hi Daniel,

I'm sure somebody will correct me if I'm wrong but I believe 'purge' and '-purge' are basically the same thing the only differences I know of are purge brings up the dialog box and -purge doesn't and as you noted above -purge allows you to purge registered applications and purge does not.

From what I understand of the purge and -purge commands it will only delete items that are not being used by the drawing therefore I would say it does not delete anything you will need.

But there's one option that's available in the -PURGE command as opposed to the dialog box version is the 'reg-apps' option. This is important because some third-party software can leave 'junk' behind in a .dwg that can muck it up and make the file size swell.

Also, just FYI:

You must specifically specify the "R" option of the "-purge" command to purge the registered applications. Simply doing "all" WILL NOT purge the applications. Good for those companies that use routines that register apps (they won't get purged by accident), but an extra step for cleaning up files from outside sources.

FYI:
SuperPurge from Manusoft does purge RegApps by default.

I started using -PU, R with some caution, not knowing if it might cause problems on those drawings created in-house with Building Systems or Cadworx, which I don't have on my machine. I've since expanded the use to include those drawings, particularly when they are having "issues" and it hasn't caused any subsequent trouble that I'm aware of.
It is quite amazing what regapps it finds, even on drawings that one would think should be "clean".

Will -pu run from autolisp? I tried it, but it just won't recognize it.

Hi,

Have you tried using (command "-purge" <arguments> ) instead? It should work.

For the arguments, type -purge at the command line and follow the prompts along noting what input it needs for what you are doing.

For example: if you want to purge all regapps, it would be:


(command "-purge" "r" "*" "n")

Let us know if you need help with that.

Thanks. Working smooth now. Sometimes its just the simple things overlooked.
