How do I purge REGAPPS pertaining to only Civil3d and other such programs?

[xnguyenFKXUE]

I have a lot of registered apps in a couple drawings I've received and it's bogging everything down. The drawing improves significantly when I purge all the REGAPPS but I loose my express tools. I want to purge all the programs except for the ones I'm using but I don't know what the registered apps are called. I also want to just look at the list of registered apps and select them instead of going through each one.

You can't purge referenced REGAPPS, so purge them all. Purging REGAPPS isn't killing your express tools, unless there is some buggy code in one or more of them.

Plenty of tools out there to view them before purging. Or you can view the list of what it purged, then UNDO. Then form the filter you want to use instead of "*"

Does -purge deletes commands like the break-line symbol or mstrech?

All those commands still work after purge regapps.

Your Express Tools probably not loaded or corrupted.

Try DEMANDLOAD, set to 3

Purge can purge unused definitions (and zero objects), nothing else.

Like blocks, layers, and so on, it can not delete commands or visible objects.

Use Purge or -purge, nothing else if you are not familiar with the things in the background.

If you use plain Autocad and your drawing is not part of a worklow like this this: Created in Toolset -> your work -> back to the Toolset

Use -ExportToAutoCAD first, use the new file then and run -purge regapp

That should be enough (for whatever you think you need)

That will delete

I just copied a temporary drawing and purge all the apps. I looks like I still have my express tools. I don't know why it got corrupted the first time around.

First off, the Purge (or -Purge) command only removes UNreferenced items. For example, if you create a new layer but don't draw anything on it, you can purge (or "delete") it. But if you draw a object on that new layer, you cannot purge it. In summary, nothing being USED can be purged.

Secondly, Regapps are not commands. A RegApp (short for "REGistered APPlication) is basically a string used as a pointer for other data that a given application may need. Read more here.  In summary, you can delete unreferenced REGAPPS all day with no fear. Why they are allowed to build up and cause DWG bloat, we'll never know.
