How to Stop OneDrive from Downloading All Files and Filling Up Computer Storage
Question details
The user needs to prevent OneDrive from automatically syncing and downloading all files to the local hard drive to preserve disk space.

- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Syncing files from cloud storage to a local computer.
- Observed behavior
- OneDrive synchronizes every file to the computer, consuming all available local disk space and leaving no room for other applications and files.
Before changing your sync settings, ensure you have an active and stable internet connection, and wait for any currently pending important file uploads to finish syncing to the cloud.
Enable OneDrive Files On-Demand to Free Up Space
Use the Files On-Demand feature to keep files in the cloud while still seeing them in File Explorer, downloading them only when you need to open them.
Files On-Demand is a built-in Windows feature that allows you to access all your cloud storage files without having to download them and use storage space on your Windows device. When enabled, your files will appear in File Explorer but will remain online-only until you double-click to open them.
Click the blue or white OneDrive cloud icon in the Windows taskbar notification area, click the Gear icon, and select Settings from the menu.
Navigate to 'Sync and backup' in the left menu, expand 'Advanced settings', and toggle on the 'Files On-Demand' option.
Open File Explorer and go to your OneDrive folder. Right-click the files or folders taking up too much space and select 'Free up space'. This removes the local copy while keeping the file securely in the cloud.

Choose Specific OneDrive Folders to Sync
Stop syncing large or unnecessary folders to your local computer entirely by configuring your folder selection settings.

Frequently Asked Questions
What happens if I simply delete a file to free up space instead of using the 'Free up space' option?
If you press the Delete key on a synced file in your local OneDrive folder, it will be moved to the Recycle Bin and deleted from the cloud and all your other synced devices. To safely remove the local copy while keeping the file in the cloud, always right-click the file and select 'Free up space'.
Why does OneDrive keep downloading files even after I enable Files On-Demand?
This usually happens if the 'Always keep on this device' option is enabled for a specific folder, or if a third-party application (like an antivirus scanner or backup tool) is opening the files in the background. Right-click the affected folder, ensure 'Always keep on this device' is unchecked, and then select 'Free up space'.
Can I temporarily pause OneDrive from syncing and downloading files?
Yes. Click the OneDrive cloud icon in your taskbar, click the gear/settings icon, and select 'Pause syncing'. You can choose to pause the sync process for 2, 8, or 24 hours, which will immediately stop all background downloads.
