Launch the OneDrive app on your Android phone, tap on the 'Me' icon at the bottom right corner, and select 'Settings'.

2
Initiate Cleanup

Look for the option labeled 'Clean up space on your device' and tap on it. Confirm the action to allow OneDrive to delete local copies of files already uploaded to the cloud.

Frequently Asked Questions

Why does OneDrive still show it is using a lot of data in my Android settings after freeing up space?

Even after you make files online-only, the Android operating system might still retain cached data, thumbnails, and metadata for those files. You can manually resolve this by going to your phone's Settings > Apps > OneDrive > Storage, and selecting 'Clear Cache'.

What happens if I simply delete a file from the OneDrive folder on my phone?

If you delete a file directly from the OneDrive folder, that deletion will sync across your account and remove the file from your cloud storage and all connected devices. To safely remove it from your phone only, always use the 'Free up space' option.

How do I know if a OneDrive file is only stored in the cloud?

Look at the status icon next to the file in the OneDrive app. A cloud icon means the file is online-only and taking up no local storage. A green checkmark means the file is downloaded and currently taking up space on your device.
