Bug in file rename?

[John Kamm]

We frequently need to rename a set of files by adding a prefix to the regular filenames. We do this to work on multiple copies of a system at a time. Adding a prefix to the original filenames using the rename utility works without a problem. Using Win FM 11.0v3 Adv.

However, when we try to rename the set of files by removing the prefix to restore the original filenames, the process fails on most of the files. I end up going into the file and changing the external file references manually, removing the prefix from the file name and file path.

Am I missing something in setting up the renaming process? Is there a trick? I have tried the process writing the renamed files to a new empty folder, to a folder with the original files, with overwrite selected and unselected (even though the new file names are always different).

Suggestions?
