How to Fix OneDrive Using Excessive Disk Space with Files On-Demand Enabled
Question details
The user needs to reduce local storage consumption by OneDrive when the Files On-Demand feature is already activated.
- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Managing local disk space and optimizing cloud synchronization settings.
- Observed behavior
- OneDrive continues to use substantial local storage space because files or folders are pinned for offline use, fully synchronized, or affected by synchronization loops.
Verify your current sync status by checking the OneDrive icon in your system tray to ensure no files are actively uploading, which could cause temporary storage fluctuations.
Free Up Space and Review Folder Sync Settings
Manually force large files to become online-only and verify which folders are set to automatically synchronize to your local drive.
Even with Files On-Demand enabled, files previously opened on your computer are downloaded and take up local space. You must manually clear them or uncheck large folders from syncing completely.
Open File Explorer, locate the OneDrive folder, right-click the files or folders taking up excessive space, and select 'Free up space'. This removes the local copy while keeping the cloud file intact.
Right-click the OneDrive cloud icon in your system tray or menu bar, click on the gear icon or 'Help & Settings', and select 'Settings'.
Navigate to the 'Account' tab and click on 'Choose folders'. Review the list of folders and uncheck any large or unnecessary directories that you do not want to be synchronized locally.
Unlink and Re-link Your PC to Fix Sync Issues
If OneDrive is stuck in a synchronization loop and ignoring your Files On-Demand settings, resetting the account connection can resolve the issue.
Try WPS Office for Lightweight and Seamless Document Management
If you are struggling with complex cloud synchronization issues and bulky software, consider switching to WPS Office. It is a highly compatible, fast, and free alternative to Microsoft Office that comes with its own efficient built-in cloud storage.

Frequently Asked Questions
Why are my online-only OneDrive files taking up disk space?
Files can take up space if they were previously opened by an application (which temporarily downloads them), if they are pinned using 'Always keep on this device', or if a synchronization error is preventing OneDrive from clearing the local cache.
What exactly does 'Free up space' do in OneDrive?
The 'Free up space' option deletes the locally downloaded copy of a file or folder, leaving a cloud icon placeholder. The actual file remains safe in your online cloud storage while freeing up physical space on your hard drive.
Will unlinking my PC from OneDrive delete my files?
No, unlinking your PC only severs the synchronization connection between your computer and the cloud. Your files remain safely stored in your online account, and any fully downloaded local files will stay on your hard drive.
How can I tell if a OneDrive file is stored locally or in the cloud?
Look at the status column in File Explorer. A blue cloud icon means the file is online-only. A green checkmark with a white background means it is downloaded locally, and a solid green circle with a white checkmark means it is pinned to always stay on your device.
