Native for macOS 15.6+ · Final Cut Pro 10.6+

Reclaim the space
Final Cut Pro forgot.

Four cache types. One sweep. Gigabytes back on your drive.

FCPX Clean scans your Final Cut Pro libraries and finds the regeneratable data you don't need — render files, proxies, optimized media and analysis files — then moves what you pick to the Trash. Your Original Media is never selectable.

Coverage

Four cache types Final Cut Pro will regenerate on demand.

Every event inside every .fcpbundle gets its reclaimable size broken down by category. You pick which types to sweep per library, per event, or across every source at once.

Render Files
Timeline & effect renders
Cached previews of your timeline. FCP rebuilds them automatically the next time you scrub through. Often the biggest win in an old project.
Proxy Media
Low-res editing copies
Small proxies used for smooth editing on lower-powered hardware. Safe to remove — originals stay intact and proxies can be re-created with one menu command.
Optimized Media
ProRes transcodes
Heavy ProRes copies generated from camera originals for performance. FCP can regenerate them, or simply edit from the originals once they're gone.
Analysis Files
Optical flow & stabilization
Slow-motion optical flow maps and stabilization analysis. FCP regenerates them the next time you apply the effect — just not instantly.
Why it's different

Not a generic disk cleaner. A specialist.

FCPX Clean reads the exact folder layout Final Cut Pro uses inside every .fcpbundle. It knows which folders are regeneratable and which contain your camera footage — and refuses to touch the latter.

Trash, never permanent

Every selected folder goes through FileManager.trashItem. Change your mind, restore from the Trash. Empty it when you're sure.

Original Media is untouchable

Folders named Original Media are displayed for visibility but can never be selected. A precondition in the cleaner refuses to trash them even if the UI were bypassed.

Proportional bars

Each library's bar is scaled to the largest one in the scan. At a glance you see where the gigabytes actually live.

Per-event selection

Tri-state checkboxes roll up from events to libraries to the whole scan. Sweep one category across every library with one click.

No account. No telemetry.

Runs entirely on your Mac. Nothing leaves your machine.

Scan any volume — internal, external, or network-mounted.

Point FCPX Clean at a drive, a folder, or a network share and it walks the tree for every .fcpbundle package. Each library appears as a row in the main table with its own per-category breakdown. Large scans are async so the UI stays responsive.

Safety model

Two lanes. No ambiguity.

Every folder inside a scanned library is classified before you see it. Caches are selectable and colored. Original Media shows up but is locked — the UI will not let you remove it.

Cache — Safe to remove
Render Files, Proxy Media, Optimized Media, Analysis Files. All four are regenerated by Final Cut Pro on demand. Some regeneration is instant (renders on playback), some takes a moment (optical flow on first use).
Selectable, color-coded
Original Media — Locked
Your actual camera footage. Shown in the library breakdown for visibility, but can never be checked, selected, or trashed. A safety guard in the cleaner refuses the operation even if the UI were bypassed.
Non-selectable
Flow

Scan. Review. Trash.

No preset cleanup recipes, no profiles, no auto-mode. You stay in control of every byte that leaves your drive.

Scan a volume

Pick a drive or folder. FCPX Clean walks the tree for every .fcpbundle and reads each library's events to size every category — internal, external, or mounted network shares.

Review & select

Each library becomes an expandable row. Four category checkboxes per row, per event, and across the whole scan. A proportional bar shows where the biggest wins are. Toggle Fixed vs Proportional to compare across libraries.

Move to Trash

A confirmation sheet shows total folders, total size, and the category breakdown. Confirm and FCPX Clean moves everything to the Trash, re-scans the libraries, and updates the numbers.
