File Rename 4+

File Rename lets you rename a number of files quickly and easily, saving you time and effort. Drag and drop one or more folders from Finder onto the application icon or dock icon and you're ready to start renaming files.

Friendly, Fast and Complete
File Rename aims to be the friendliest, fastest, most complete batch/bulk file renaming tool for OS X. With over 12 different rename options, it can handle most renaming tasks (and if it doesn't do what you need, just drop us an email and we'll try our best to implement it, as we are always looking to improve the application).

Real-Time Preview and Undo Feature
File Rename displays a real-time preview of the renamed files so you can confirm the changes before actually performing any renaming. You can also use the Quick Look feature to check the contents of the files you are renaming. Should you decide after a rename that you want to revert the changes, there's an undo feature.

For Digital Photographers
File Rename makes it quick and easy for photographers to create detailed filenames for all their photos by adding number sequences, date information of when the photo was taken and EXIF metadata such as: width & height, aperture, ISO, focal length, F-number and shutter speed.

For Music Enthusiasts
File Rename is ideal for renaming audio files such as MP3s. As long as the audio files contain the relevant metadata, you can standardise the names of audio files, by including information such as: title, artist, album, album artist, genre, composer, year, track number, track total, disc number, disc total, bit rate, sample rate and duration.
