I have a ACAD file that takes a long time to open. It slows down on the .ac$ files. How does the .ac$ files affect the opening of a drawing? I thought these file where only created in an active file that held undo and other temp info for this one session.

When I hit F2 to view the info it reads

Reslove Xref "a-fp01.dwg"

I have never seen this before and I don't know what I am suppose to resolve.

I have purged, audited, wblocked, detached, reattached. Still it takes its sweet time opening.


What should I do to "Resolve Xref"????

Thanks
