File and MP3 Renamer 2006
Full user review
"Worth downloading for the file renamer alone"
I haven't used the MP3 portion so my comments are confined to file renaning only. Renamer allows a subset of regexp-style changes without resorting to scripts or shells. Places itself on Windows Explorer context menu. Clean interface.
None that I've found.
This is not the kind of tool that you use extensively so it's difficult to evaluate but for me it did what it says it would do and did it nicely.
