Here in my job we do this: there is a DOC file with all the filename codes in the project, and every code is unique.
The DWG files have this format of filename:
DE-4719.02-862-ASX-008=0.dwg
Every code on the filename have a meaning, like "4719" is the currently project, "862" is from where the money is coming to execute that specific drawing...and the list goes on....
As revisions are made in the project, we simply change the revision in the filename AND in the drawing, like: DE-4719.02-862-ASX-008=A.dwg
But the revisions are fully controled by that DOC file that says all the changes made to every file, who e when changed it, and to where the file is gonna be sent.


DE-4719.02-862-ASX-008=0.dwg
DE-4719.02-862-ASX-008=A.dwg
DE-4719.02-862-ASX-008=B.dwg
DE-4719.02-862-ASX-008=C.dwg

In the company's network, only the last revision appears, the old revisions are moved to a folder called "Old" in the same place where the actual revision is.
Many times we had to recover files from the "old" folder, so it's important to keep your old revisions.
