There is an ancient solution to this on the forum.
It is very, very, old !
Personally, these days, I think that this is what to do.
It is easy to do another rename to get these to final form.
This was written by @Leo long before he was a Directory Opus Developer.
He really was, but he didn't have to work for GPSoft yet.
I still have a button for it.
This thread was copied over from the old forum.
The comments are very old an out of context today.
So what you need is a safe place to copy the old script, DupeFile.vbs to.
/dopusdata\Scripts is probably a good choice.
The button code is then just this:
@set NumDupes = {dlgstring|Number of duplicates to create:|10}
/dopusdata\Scripts\DupeFile.vbs {filepath$} {$NumDupes}
It does have a pop-up for the number of copies needed.
This will get you any # of duplicate files appended intelligently by a properly padded _# .
Other than these solutions, you'll probably need to write a new script.
