FCP CleanX.

Final Cut Pro keeps files it knows how to recreate inside every library: render files, optimized media, proxies, analysis files, audio waveforms and thumbnails. Over many edits, they end up taking a lot of disk space. Final Cut Pro can delete generated files, but you have to open it and go through each library one by one, without seeing the size of each category.

FCP CleanX automates that cleanup without opening Final Cut Pro. On launch, the app finds every .fcpbundle library on every drive (internal disk, external SSDs, RAID) through Spotlight, groups them by drive, shows the recoverable space category by category, then cleans all the selected libraries in one click.

A tool that deletes files has to be flawless. FCP CleanX applies three independent, hard-coded safeguards: the Original Media folder that holds the footage is excluded from the scan itself, not just from deletion; only the cache folders Final Cut Pro is known to use can be emptied, and only inside a library; projects, events and settings are ignored in every case. Cleaning is blocked while Final Cut Pro is open, and by default everything goes to the Trash, so it can still be recovered.

The app is sold directly: a full 7-day trial with no credit card and no account, then a 12 euro license, paid once, valid for life with updates included. After the trial, the analysis stays available and only cleaning requires a license.

1. 01Automatic detection of Final Cut Pro libraries on every drive, grouped by drive
2. 02Size of each category before deleting: render files, optimized media, proxies, analysis files, waveforms, thumbnails
3. 03Precise selection of what to empty, library by library, with search and select all
4. 04One click cleans every selected library, with a progress bar and time remaining
5. 05Moves files to the Trash by default, so you can change your mind
6. 06Original media, projects and events never touched, cleaning blocked while Final Cut Pro is open
7. 07Drag and drop a library manually if it was not detected
8. 08Interface in French and English

FCP CleanX is a native app written in Swift, with a SwiftUI and AppKit interface. It weighs less than 1 MB, runs on macOS 13 Ventura and later, on Apple Silicon and Intel, and supports libraries from recent Final Cut Pro versions, including FCP 11. Library detection relies on the macOS Spotlight index.
