Renamer4Mac makes it really easy to rename a big number of files according to a preset pattern. It lets you rename your files in many different ways:

• Search & replace
• Insert/overwrite of text
• Number the files
• Convert upper/lowercase

All can be done with an easy user interface and real-time preview, so you can see how the files will be named just while you're configuring!

Renamer4Mac is no longer maintained by me. Please visit it at its new home.

• Presets: Renamer settings can be saved and restored
• Improved keyboard control
• Some smaller improvements
