Excess Object Groups

I have a question that I hope someone can help me with. I have several drawings that have tens of thousands of unnamed object groups. In the Object Groups dialog box, if i check the "include unnamed" box I can see many unnamed groups. The largest name is *A64140. This particular drawing is a simple window elevation.

My question is... Does anyone know how to clean out these thousands of unnamed groups. They make the drawing files HUGE. this drawing is 12,845 kb. If I copy the entities from this drawing to a new, clean sheet, the drawing file drops to about 515 Kb.

Any help would be greatly appreciated.

Thanks,

Have you tried 'purge'?

I tried purge, does nothing for me. There used to be a command called RemLayerFilters that used to work really well. This does not work in 2006 however.

Autocad has never had a RemLayerFilters command. It must have been a custom lisp routine that you were running.

You can find it here: http://discussion.autodesk.com/forums/thread.jspa?threadID=70806

Can't you just select those unnamed groups in the dialog window and then hit the "Explode" button? That should remove the groups from the list.

Otherwise, just WBLOCK this drawing out to a new file. That will strip out all the irrelevant and unnecessary entities.
