What happened when you installed that utility on your Windows 7 PC, just like you did long ago on your XP PC?
- Could you install it?
- Could you run it?
- Did it work?
It might help if you tell us the name of the utility and where you downloaded it from.
When using XP I had a right-click utility that allowed me to add a descriptive text file, in the same directory, to any file list in explorer. Is there a Windows 7 equivalent?
