How to Free Up C: Drive Space Used by OneDrive Files
Question details
The user needs to reduce local disk usage on their C: drive that is being consumed by synchronized OneDrive files.
- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- The local C: drive is running out of storage space because OneDrive is downloading and storing synchronized files locally.
- Observed behavior
- OneDrive stores synchronized files locally by default. Users want to utilize features like Files On-Demand and Choose Folders to keep files online and free up local storage, but sometimes encounter missing settings or unresponsive icons.
Ensure your computer has an active internet connection so OneDrive can successfully communicate with the cloud and update file statuses to online-only without causing sync errors.
Enable Files On-Demand and Free Up Space
Use OneDrive's built-in Files On-Demand feature to keep your files in the cloud, downloading them only when you need to open them.
Files On-Demand allows you to see all your cloud files in File Explorer without having to download them. Files marked as online-only take up practically zero space on your computer.
Click the blue or white OneDrive cloud icon in the Windows taskbar notification area, click the Gear icon, and select Settings.
Navigate to the Sync and backup tab (or Settings tab in older versions) and toggle on 'Save space and download files as you use them' under the Files On-Demand section.
Open File Explorer, locate your OneDrive folder on the C: drive, right-click the files or folders taking up excessive space, and select 'Free up space'. The file status icon will change to a blue cloud, indicating it is now online-only.
Stop Syncing Specific Folders
Prevent large folders from downloading to your local drive by entirely excluding them from synchronization.
Move the Local OneDrive Folder to Another Drive
Relocate the entire OneDrive synchronization folder to a secondary internal or external drive if your C: drive remains too small.
Save C: Drive Space by Switching to WPS Office
If your C: drive is consistently full, installing heavy software like Microsoft Office can exacerbate the problem. Switch to WPS Office—a powerful, lightweight, and free alternative that occupies significantly less disk space while fully supporting all your Word, Excel, and PowerPoint documents.
- 1. Download the lightweight installer: Visit the official WPS website and download the free WPS Office installation package.
- 2. Install on your PC: Run the installer. Notice how quickly it installs and how little C: drive space it consumes compared to traditional office suites.
- 3. Work directly in the cloud: Open WPS Office and utilize the built-in WPS Cloud to create, edit, and save files directly online, bypassing local storage entirely.
Frequently Asked Questions
Why is the 'Save space and download files as you use them' option missing in my OneDrive settings?
This option might be hidden if you are using an older version of Windows, an outdated OneDrive client, or if your organization's IT administrator has disabled the Files On-Demand feature via network group policies.
What should I do if clicking 'Free up space' does not remove the files from my C: drive?
Ensure your OneDrive application is actively running and connected to the internet. Sometimes, the file explorer icons get stuck. Try restarting the OneDrive client or rebooting your computer to force the file statuses to update to the cloud icon.
Will selecting 'Free up space' permanently delete my files?
No. Selecting 'Free up space' only removes the downloaded local copy from your C: drive to save space. The original file remains safely stored in your online OneDrive account and can be re-downloaded simply by double-clicking it.
Can I store my OneDrive local folder on a portable external hard drive?
Yes, you can move your OneDrive directory to an external drive to save C: drive space. However, the external hard drive must be plugged in whenever the computer is turned on and OneDrive is syncing; otherwise, OneDrive will display error messages and pause synchronization.
