Splice Folder Taking Up Space on Mac: Safe to Delete?

Yes, but read this firstDiskmack safety tier: Caution

~/Splice

Yes, you can delete the Splice folder, but check your music projects first. Everything in ~/Splice is a sample you licensed through your Splice account, and you can re-download all of it later without spending credits again. The catch: any Ableton, Logic, or FL Studio project that references those files by path will open with missing samples. Consolidate the projects you care about, then clean.

What it is

The Splice desktop app downloads every sample you license to a folder in your home directory, ~/Splice by default. Inside, samples are organized into folders by sample pack, mostly as WAV files. This is real content you paid credits for, not a cache: loops, one-shots, presets, and full packs from the Splice catalog.

It grows fast because WAV files are uncompressed and because Splice downloads a local copy of everything you pick up. A casual user might have a few gigabytes here. A producer who has been on Splice for a couple of years can easily be sitting on tens of gigabytes of packs they grabbed for one project and never opened again.

Is it safe to delete?

Deleting the folder does not delete your purchases. Your library lives in your Splice account, and anything you remove locally can be re-downloaded later. Re-downloading uses your plan's bandwidth, not credits, so you are not paying twice. In that sense the folder is safe to clear.

The real risk is your DAW projects. Ableton, Logic, and FL Studio reference audio files by their path on disk. Delete ~/Splice and every project that pulled a sample straight from it will complain about missing files the next time you open it. Before you clean, open the projects you still care about and consolidate them (Ableton: File > Collect All and Save; Logic: save the project with assets copied in). Diskmack identifies the Splice folder automatically and cleans it the safe way, moving files to the Trash instead of deleting them outright.

How to check its size

In Finder: In Finder, choose Go > Go to Folder (or press Shift-Command-G), type ~/Splice, and press Return. Select the Splice folder, then press Command-I to see its size.

In Terminal:

du -sh ~/Splice

How to clean it

Open any DAW projects you still care about and consolidate them so the samples are copied into the project itself. In Ableton Live that is File > Collect All and Save. In Logic Pro, save the project with assets copied in.
Open the Splice app and confirm your library lists the samples you have licensed. They belong to your account, so the local copies are not your only copies.
Decide whether to move instead of delete. The Splice app settings let you change where samples are stored, so pointing it at an external drive keeps everything intact and frees your internal disk.
To delete: in Finder, go to ~/Splice and drag the packs you no longer use (or the whole folder) to the Trash.
Empty the Trash once you are sure no project you need references those files.
When you want a sample back, re-download it from the Splice app or website. It costs bandwidth, not credits.

Re-downloaded samples land wherever the Splice app is currently set to store them, which may not match the old paths your projects expect. You might still need to relocate files inside your DAW.

Will it come back?

Yes, at exactly the rate you keep using Splice. Every sample you license downloads a local copy, and every re-download puts the file right back. If you have an active subscription and produce regularly, the folder will refill within months. The lasting fix is moving the library to an external drive through the app's settings, then treating your internal disk cleanups as routine pruning of packs you have stopped using.

Common questions

Will I have to pay credits again to re-download deleted samples?

No. Samples you have licensed stay in your Splice account, and re-downloading them uses your plan's bandwidth, not credits. You can bring back anything you deleted without paying twice.

Why does my project say samples are missing after I deleted the folder?

DAWs reference audio files by their location on disk, and the location no longer exists. Re-download the samples from Splice, then use your DAW's missing-file dialog to point the project at the new copies. Consolidating projects before you delete avoids this entirely.

Can I move the Splice folder to an external drive instead of deleting it?

Yes, and for most producers it is the better option. Change the storage location in the Splice app's settings rather than dragging the folder yourself, so the app knows where everything went. New downloads will go to the drive from then on.

Should I delete ~/Splice if I canceled my subscription?

Be careful here. Splice's license lets you keep using samples you already downloaded after you cancel, but without an active plan you should treat the local files as your primary copy. Back the folder up somewhere before removing it from your Mac.
