In XP...
1. Highlight all the files in s subfolder in Windows Explorer with the mouse
2. Right click on one of the files and select 'Rename' at the bottom of the popup menu
3. Type in the 'Base' filename you want, complete with the file extension
4. Hit the return key
All the files will now be renamed with that name, with the new filename followed by a number in brackets.
If you screw it up, you can always Undo by pressing Ctrl-Z
Hope that helps...![]()
