Did you have too many OS install in your system and want to get an universal renaming solution then you need to give a chance to Metamorphose. It is an open source software, that mean you don’t need to pay anything no matter where you going to use it. You can use it on Windows, Mac, Linux and FreeBSD. However, you need to have separate installer pack for each system.

The most interesting part of this renaming program(Metamorphose) is, you can undo renaming operation in case of mistakes. Another noticeable feature is, it can rename MP3 files according to their ID3 tags and rename image files according to their Exif tags.

Here is a feature list:

• Preview every item to be renamed before committing changes.
• Load all files in directory and in subdirectories (recursive renaming).
• Undo renaming operation in case of mistakes.
• Regular expression support throughout.
• Rename MP3 files according to their ID3 tags.
• Rename image files according to their Exif tags.
• Full unicode support means any character from any language can be used.
• Use of all allowed characters under Windows and OSX, all except ‘:’ in Linux.

This is really a most powerful and professional tool on renaming and it really strange it’s free. If you love to donate, I think you should donate on this project.
