Fix OneDrive Free Up Space Not Removing Files on Mac
Question details
The user is attempting to use the Free Up Space feature in OneDrive on a Mac to make files online-only, but the files continue to occupy local hard drive storage and remain available offline.
- Product
- OneDrive
- Device & OS
- macOS
- Scenario
- Trying to optimize Mac local disk space by offloading synced OneDrive files to the cloud.
- Observed behavior
- After selecting Free Up Space, files do not convert to zero bytes locally; they continue to consume physical disk space and remain fully accessible offline.
Ensure that your Mac is connected to a stable internet network and wait for the OneDrive app to display an 'Up to date' status, as files recently copied from external drives must fully sync before local space can be freed.
Unpin Files and Check for Unsupported File Types
Use this solution to ensure that files are not locked locally by the 'Always Keep on This Device' setting or unsupported by macOS File Provider.
In macOS, the File Provider system manages how cloud files count toward local disk usage. If a file is pinned (marked to always stay on the device) or is an unsupported type like a OneNote shortcut, the 'Free Up Space' command will not successfully release its local storage footprint.
Open Finder on your Mac and navigate to your synchronized OneDrive folder from the sidebar.
Look for files or folders displaying a solid green circle with a white checkmark. This icon indicates that the item is pinned for offline use.
Right-click (or Control-click) the pinned files or folders and ensure that 'Always Keep on This Device' is unchecked. Then, click 'Free Up Space' again.
Review the remaining files for specific types such as .url or OneNote shortcuts, which macOS may cache locally regardless of OneDrive settings.
Reset the OneDrive Application
Resetting OneDrive forces the application to rebuild its sync cache, which can resolve persistent status icon and storage allocation issues.
Test with a New macOS User Profile
Creating a temporary user profile helps determine if the Free Up Space failure is caused by system-wide software conflicts or a corrupted local user directory.

Frequently Asked Questions
Why do files still show a local file size after I select Free Up Space?
On macOS, the File Provider system manages cloud files. Even when files are successfully marked as online-only, macOS may still count their cached metadata or unsupported item types (like shortcuts) toward local disk usage.
What does a cloud icon mean next to a file in Mac OneDrive?
A cloud icon indicates that the file is an 'online-only' file. It does not occupy space on your Mac's hard drive and will only be downloaded to your device when you double-click to open it.
How do I know if a file is permanently downloaded or pinned?
Pinned files have a solid green circle with a white checkmark icon. This indicates the file has been set to 'Always Keep on This Device' and will not be removed by standard automatic storage cleanup.
Can copying files from an external drive prevent Free Up Space from working?
Yes. If you recently copied large folders from an external drive into OneDrive, the app must finish uploading every file to the cloud first. You cannot free up local space until the sync is 100% complete.
