Clear Lightroom CC Cache on Mac
Clearing the Lightroom CC cache frees space by reducing the local copies of your photos, and your originals stay safe. Start inside the app under Lightroom > Settings > Local Storage, where you can lower the cache size or stop storing originals. Unsynced photos are kept either way.

Clear it from inside Lightroom CC first
The safest way is the option built into the app: Lightroom > Settings > Local Storage (lower the cache size or stop storing originals; unsynced photos are kept)
Lightroom CC cache folders you can clear
Lightroom CC has no separate cache folder. Its folders hold settings and your own data, so there is nothing to clear safely by hand.
What the Lightroom CC cache holds
Specific to Lightroom CC
The main cache is the Lightroom Library bundle in your Pictures folder. It holds local copies of cloud photos, previews and pending uploads, and it grows large when local copies of all originals are kept. Clearing helps when that bundle is taking up much of your disk, which can be anywhere from 5 GB – 100 GB. Check its size first and make sure no imports are waiting to sync.
What happens after you clear the Lightroom CC cache
Once everything has synced, the bundle can be rebuilt, so clearing it does not cost you your cloud library. Unsynced imports exist only in the bundle, so confirm they have uploaded before you clear anything. Creative Cloud components and sign-in data are shared with other Adobe apps and stay in place. Your originals remain in Adobe cloud storage tied to your Adobe ID.
