How to Safely Delete the OneDrive Sync Client Suite Folder on Mac

Product: Microsoft OneDrive
Device & OS: macOS
Scenario: Reclaiming local disk space after uninstalling the OneDrive desktop application.
Observed behavior: The local OneDrive Sync Client Suite folder continues to occupy significant disk space (e.g., 34 GB) despite the OneDrive application having been uninstalled.

Before you start

Solution 1Recommended

Verify Uninstallation and Delete the Local Cache Folder

Ensure OneDrive is completely removed and safely delete the leftover Sync Client Suite folder to free up local disk space.

If you no longer use the OneDrive desktop app and rely solely on the web version, the Sync Client Suite folder acts as an orphaned local cache. Deleting it will not remove your files from the cloud, provided the sync client is completely inactive.

Check Applications

Open your Mac's Applications folder to confirm the OneDrive app is fully uninstalled and no longer running in the background.

Locate the Leftover Folder

Open Finder on your Mac and navigate to the location of the 'OneDrive Sync Client Suite' folder that is taking up storage space.

Delete and Empty Trash

Drag the 'OneDrive Sync Client Suite' folder to the Trash, then empty the Trash to permanently reclaim the occupied local storage.

Active Sync Warning: Never delete this folder if the OneDrive application is still installed and running, as it will actively trigger deletions in your cloud storage.

Frequently Asked Questions

Will deleting the local OneDrive folder delete my files in the cloud?

No, as long as the OneDrive application is completely uninstalled or not actively running, deleting the local cache folder will not affect the files securely stored on OneDrive.com.

Why is the OneDrive Sync Client Suite folder so large after uninstallation?

The folder retains offline copies of your files, local caches, and installation remnants. Uninstalling the app removes the software itself but intentionally leaves these data folders behind to prevent accidental data loss.

What should I do if OneDrive is still syncing?

If the OneDrive app is still installed and actively syncing, do not manually delete the local folders. Doing so will command the cloud server to delete the files online as well. Always uninstall the application first.
