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 files or folders from Finder onto the app and you're ready to start renaming.

Friendly, Fast and Complete
File Rename is a fast, friendly and complete batch/bulk file renaming tool for macOS. 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).

Real-Time Preview and Undo Feature
The app displays a real-time preview of the renamed files so you can confirm the changes before actually performing any renaming. Should you decide after a rename that you want to revert the changes, there is always the undo feature.

For Digital Photographers
The app 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
The app is ideal for renaming MP3 audio files. 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.

For Techies (via in-app purchase)
For the more technical minded, the app offers an advanced section allowing the use of powerful regular expressions for finding and replacing in filenames.

Simultaneous Rename Options
The rename options can be used in conjunction with each other making complex renaming a simple task. An intuitive user interface makes it easy to see at a glance which options are currently in use.
