# How to Clean Up Final Cut Pro and Logic Pro Storage

> Remove generated media and unused audio through Final Cut Pro and Logic Pro while preserving originals, backups, and project recovery points.

Published: 2026-09-04

Final Cut Pro and Logic Pro mix rebuildable output with source media, recordings, and project databases. The safe cleanup path is to let each app remove what it owns, then use a disk map to find the project worth opening.

Before deleting anything, make a current project backup and confirm where the original media lives. A large folder is not automatically disposable: it may contain generated files, or it may be the only copy of a recording.

## Cleaning Up Final Cut Pro

### Delete Generated Library Files

Final Cut Pro can create render files, optimized media, and proxy media. Select the library, event, project, or clips you want to clean, then choose **File > Delete Generated Library Files** or the matching generated-files command.

- Render files can be regenerated automatically when Final Cut needs them.
- Optimized and proxy media can also be regenerated, but you must start that work again and wait for it to finish.
- Original media is not part of this generated-files command. Confirm that the originals are still online before removing optimized or proxy copies.

If playback depends on proxy media, switch the viewer back to optimized/original media before the final share. Apple notes that generated-file deletion can affect external as well as library-managed media, so use the selected scope shown in Final Cut rather than deleting folders in Finder.

### Manage Final Cut Pro Backups

By default, Final Cut Pro saves library database backups in `~/Movies/Final Cut Pro Backups`. The location can be changed in the library's storage settings. These backups do not include media, and Final Cut automatically removes backups older than several days.

That makes backups a recovery tool, not usually the main source of a full disk. Open **File > Open Library > From Backup** to confirm what is available before removing a backup manually. Keep a known-good backup until the project and library open correctly from their archived location.

## Cleaning Up Logic Pro

### Remove Unused Audio Takes

Logic keeps source recordings even after a region leaves the Tracks area. Once final takes, comps, hidden tracks, and Track Alternatives are settled, open the **Project Audio Browser**, choose **Edit > Select Unused**, review the selection, then use the browser's **Audio File > Delete File(s)** command when you intend to move those files to Trash.

Pressing Delete can remove an item from the project while leaving the audio file on disk, depending on the selected command. More importantly, an audio file can be shared with another project. Consolidate project assets first if you cannot prove ownership. Logic's **Optimize File(s)** command edits source audio destructively, so it is not a general cleanup shortcut.

### Manage Freeze Files and Plug-in Caches

Frozen tracks trade disk space for lower CPU use. Unfreeze only projects you are archiving and can render again. Do not wipe Audio Unit caches for storage: they are usually small, and deleting them forces plug-in validation without addressing project media.

## Using a Disk Analyzer

A disk map should help you choose which project to open, not which internal file to remove. Mole's Analyze view can show which `.fcpbundle`, Logic project, or media folder is large. Reveal the owner in Finder or open the project in its app, then use the supported cleanup command. Mole should not guess which take, proxy, or backup matters to your edit.

The recovery cost is the useful way to read the map:

| Content | Best removal path | Recovery cost |
|---|---|---|
| Final Cut render files | Delete Generated Files in Final Cut | Re-render time |
| Final Cut optimized or proxy media | Delete Generated Files in Final Cut | Manual regeneration and download/read time |
| Final Cut library backups | Review backup location in Final Cut | Loss of a restore point |
| Logic unused recordings | Project Audio Browser after final edit | Potentially irreversible if shared or not backed up |
| Original media and project files | Archive or move deliberately | May be irreplaceable |

## FAQ

### Are Final Cut render files safe to delete?
Yes, when you remove them through Final Cut Pro. They can be regenerated, although the next playback or export may take longer while rendering catches up.

### Does Mole clean project internals automatically?
No. Mole maps disk usage and can help locate the large project. Final Cut Pro and Logic Pro should decide which generated or unused project files to remove.

### Should I delete optimized media?
Only when the original media is available and you accept the time needed to regenerate optimized copies. If the originals are offline or hard to recover, keep the optimized media until the project is safely archived.
