Question details
The user wants to configure OneDrive to store files online-only in order to free up local storage space on their device without losing access to the files.
- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Freeing up local laptop or PC storage while maintaining seamless access to OneDrive synchronized files.
- Observed behavior
- Synchronized OneDrive files are consuming local disk space, and the user wants them to remain visible in File Explorer but use zero local storage until they are actually opened.
Before changing your synchronization settings, ensure you have an active and stable internet connection so OneDrive can properly update your file statuses and apply the changes.
Enable OneDrive Files On-Demand
Use the Files On-Demand feature to make your files online-only. This keeps them visible in File Explorer but removes the local file data to free up your hard drive.
By enabling Files On-Demand, you can see all your files in File Explorer without having to download them. When you open an online-only file, it downloads to your device and becomes locally available.
Click the OneDrive cloud icon located in the Windows notification area (system tray), click the gear icon, and select 'Settings'.
In the Settings menu, navigate to the 'Sync and backup' tab, then click on 'Advanced settings'.
Select the option to 'Free up disk space'. This will convert your downloaded files to online-only files, clearing up local storage while keeping the file icons visible in File Explorer.
If you are planning to move files manually, go to 'Sync and backup' > 'Manage backup' to review or disable backup settings for crucial folders like Desktop or Documents.

Frequently Asked Questions
How can I tell if a OneDrive file is online-only or stored locally?
In File Explorer, check the status icon next to your file. A blue cloud icon indicates the file is online-only and uses no local space. A green checkmark means the file is downloaded and taking up space on your hard drive.
Can I open online-only files when I don't have internet access?
No, online-only files require an active internet connection to download and open. If you know you will be offline, right-click the file beforehand and select 'Always keep on this device'.
Will deleting an online-only file remove it from my OneDrive cloud storage?
Yes. If you delete a synchronized file or folder from your File Explorer, regardless of whether it is stored locally or is online-only, it will be moved to the OneDrive recycle bin and deleted from the cloud.
How do I change a file from online-only back to always available locally?
Open File Explorer, locate the online-only file or folder with the blue cloud icon, right-click on it, and select 'Always keep on this device'. The file will download, and the icon will change to a solid green circle with a white checkmark.
