Fix OneDrive Using C Drive Space with Files On-Demand Enabled
Question details
The user's local C drive is running out of space because OneDrive is consuming local storage, despite having ample cloud capacity and Files On-Demand enabled.
- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- Managing local computer storage while syncing files with cloud services.
- Observed behavior
- OneDrive files are being saved locally on the C drive, depleting local storage space even when cloud storage is available and Files On-Demand is turned on.
Ensure you are logged into your OneDrive account with an active internet connection, and check your Windows Storage settings to see exactly how much C drive space is currently being consumed by your OneDrive folder.
Use the Free Up Space Feature for Local Files
Use this method to instantly remove the local copies of files that have already been downloaded to your C drive, keeping them safely stored in the cloud.
Even with Files On-Demand enabled, files that you open are temporarily downloaded to your local drive for quick access. Over time, these locally cached files can accumulate and take up significant space on your C drive.
Press Windows Key + E to open File Explorer and navigate to your OneDrive folder located in the left sidebar.
Highlight the specific files or entire folders that are taking up too much local space.
Right-click the selected items and choose "Free up space" from the context menu. The file status icons will change to a blue cloud, indicating the local copy has been removed but remains in your cloud storage.
Verify and Re-enable Files On-Demand Settings
Sometimes the Files On-Demand setting gets disabled accidentally or after a system update. Re-enabling it ensures new files stay in the cloud by default.
Move the OneDrive Folder to Another Drive
If your C drive is inherently small, you can move your entire OneDrive sync folder to a secondary drive (like D: or E:) that has more storage capacity.
Switch to WPS Office for a Lightweight, Cloud-Friendly Experience
If managing heavy Microsoft integrations and local storage issues is slowing down your PC, consider switching to WPS Office. It provides a lightweight, highly compatible alternative to Microsoft Office, complete with its own efficient built-in cloud storage to save your local drive space.
- 1. Download WPS Office: Visit the official WPS website and download the free installation package.
- 2. Install the Software: Run the installer and follow the quick setup instructions to install WPS Office on your PC.
- 3. Sign In for Cloud Benefits: Open the application and create a free account to unlock 1GB of dedicated WPS Cloud storage for your documents.
Frequently Asked Questions
Why are my OneDrive files downloading automatically to my C drive?
Files may download automatically if a third-party application, such as an antivirus or backup software, scans the OneDrive folder. Alternatively, you may have previously right-clicked the folder and selected "Always keep on this device."
What does the solid green checkmark icon mean in OneDrive?
A solid green circle with a white checkmark means the file is marked as "Always keep on this device" and will permanently take up local C drive space. An outlined green checkmark means it was downloaded temporarily when you opened it.
Will using "Free up space" delete my files from the cloud?
No. Selecting "Free up space" only deletes the local copy of the file from your computer's hard drive to save space. The original file remains safely stored in your OneDrive cloud account.
Can I use Files On-Demand if I don't have internet access?
Files that have a blue cloud icon next to them require an internet connection to open. If you need to access files offline, you must right-click them and select "Always keep on this device" while you are still connected to the internet.
