Thanks for BRU, it's awesome. The only thing I've tried that compares is NameWiz. I've with use found your tool better though, and on top of it - free

I use the Numbering feature for renaming my photos. I've discovered that if I rename wrong, and want to update the same files - adjusting the serie with an increment within the same range, BRU throws warnings that a file name with the same name already exists.
Example:
001.jpg
002.jpg
003.jpg
004.jpg
Renumber to:
002.jpg
003.jpg
004.jpg
005.jpg
If I set the numbering to start on 002 instead of 001, BRU will then throw warnings 3 times, as it finds 002-004 when renaming.
Guess it can't be classified as a "bug", but it can surely be worked around using temp files or arrays that resorts the naming order so that no file gets the same name

The feature request is presets to create "web-safe" file/folder names. Perhaps also DOS-compliant names.
