Deleting revision log in Logix / Studio 5000 .ACD file?

If you open a RSlogix / Studio 5000 .ACD file with notepad, it shows a list of every "save" that has ever been performed on the file. A lot of my projects start from copies of older projects, so this log has grown enormous, and the dates go back a few years. I've tried just deleting lines from the log, but it corrupts the file and can no longer be opened by Logix/Studio 5000.

Does anybody know of a way to clear the log without corrupting the file?

Thanks!!

Use the Save As to save the file to a .L5K and then import the L5K as a new project. History is erased.

That worked perfectly- thanks a bunch!
