Yes that was the "Test For Duplicates" script, and no, it initially didn't work on Linux/MAC. Any script that accesses the file system has the potential to be written to be not cross-platform thanks to the directory-separator differences ( "/" vs. "\" ). Obviously this can be fixed by use of the DIR-SEPARATOR constant. My problem was with the searchpath separator differences (";" vs. ":") for which the equivalent fix:- SEACRCHPATH-SEPARATOR, only exists 2.7.4 onwards.

The thing that's going to become important soon(ish) is the GIMP version.

P.S. Being able to update the details on my script would be useful as the built-in fix for SEARCHPATH-SEPARATOR breaks my script so it can't claim to work on 2.7.x any more, and I don't think I'd want to claim compatibility with an ill-defined moving target anyway.

Ah, I should have considered that your script manipulates the folder index of the file system, duh!

Is there no reliable way to detect OS in PyGimp, so you could make the "separator" type a variable, or are you just stuck with limited internal procedures to manipulate the file system?
