Hi Corion,
Prompted by the link you gave, I switched to my C:/_32 directory which contains a file named 'switches.txt'. I tried:

C:\_32>perl -MWin32 -e "print Win32::GetFullPathName('SwitcHes.txt')
C:\_32\SwitcHes.txt
[download]

Not much joy with that .. it just reproduces what I gave it.
However:

C:\_32>perl -MWin32 -e "print Win32::GetLongPathName('SwitcHes.txt')
switches.txt
[download]

That looks more promising !!
I should be able to make use of that in my script without going to too much trouble at all.

Incidentally, I did see that post of yours ... but didn't get around to actually reading the thread :-(

Cheers,
Rob
