How to Free Up Space in OneDrive (2026)
“Free up space in OneDrive” means two completely different things, and people mix them up constantly:
- Local disk space — your computer’s hard drive is full because OneDrive downloaded everything.
- Cloud storage — your OneDrive account hit its quota (5 GB free, or your plan’s limit) and won’t accept new files.
Here’s how to fix each.
Free Up Local Disk Space (Files On-Demand)
When OneDrive files are taking up room on your actual hard drive, you can make them online-only — they stay in the cloud and show in File Explorer, but the local copy is removed until you open them.
One file or folder
- Open File Explorer and find the file or folder in OneDrive.
- Right-click it.
- Choose Free up space.
The icon changes to a white cloud outline (online-only). Double-click it anytime to download it again on demand.
Everything at once
To set your whole OneDrive to online-only by default:
- OneDrive icon > gear > Settings > Sync and backup > Advanced settings.
- Make sure Files On-Demand is on.
- Then right-click the top-level OneDrive folder > Free up space.
This can recover many gigabytes instantly without deleting anything. For the full explanation of the cloud/checkmark icons, see what OneDrive Files On-Demand is.
Note: “Free up space” does not reduce your cloud quota — the files are still in OneDrive. It only reclaims room on your PC.
Free Up Cloud Storage (Your OneDrive Quota)
When OneDrive.com says you’re out of space and files stop uploading, you need to delete things from the cloud.
Find your biggest files
- Go to OneDrive.com and sign in.
- Click the Storage metrics link (gear > Options > Manage storage), or sort any folder by File size (largest first).
- Delete the large items you no longer need.
Empty the Recycle bin
This is the step most people miss — deleted files still count against your quota for 30 days.
- In OneDrive.com’s left sidebar, click Recycle bin.
- Click Empty recycle bin.
That space comes back immediately.
Other quota wins
- Photos — the camera roll backup can be huge. Review Photos and delete duplicates/screenshots.
- Old versions — OneDrive keeps version history, but it generally doesn’t count against personal quota; for work accounts, large libraries can. Check Manage storage for what’s using the most.
- Shared with you doesn’t count — only files you own use your quota.
Check How Much Space You Have
- Cloud: OneDrive.com shows a storage bar at the bottom-left, or open Manage storage for a breakdown.
- Local: Windows Settings > System > Storage shows what OneDrive is using on your drive.
Troubleshooting
”Free up space” option is missing
Files On-Demand isn’t enabled. Turn it on: OneDrive icon > gear > Settings > Sync and backup > Advanced settings > Files On-Demand.
I freed up space but my disk is still full
“Free up space” only affects OneDrive files. Use Windows Storage Sense or Disk Cleanup for system files, downloads, and the Windows Recycle bin (separate from OneDrive’s).
Files keep re-downloading
Some app or backup tool is opening them, which pulls them back local. Set the folder to Free up space again, and check what’s accessing it.
Still “storage full” after deleting
You didn’t empty the OneDrive Recycle bin — deleted files hold quota for 30 days. Empty it.
