If OneDrive is telling you storage is full — or you just want to clean things out — the process is straightforward once you know where to look. The short version: delete files you don’t need, empty the Recycle Bin (most people skip this), and optionally switch to Files On-Demand so files stay in the cloud without taking up local space. This guide covers all of it.
One thing to know upfront: Microsoft gives you 5GB free with OneDrive. That fills up faster than you’d expect, especially if Windows automatically backs up your Desktop, Documents, and Pictures folders — which it does by default on many setups.
What’s Actually Using Your OneDrive Space
Before deleting anything, it helps to see what’s taking up the most room. The quickest way to check:
- Go to onedrive.live.com and sign in
- Click the gear icon in the top right, then Options
- Select Manage storage
This shows a breakdown of your usage. Alternatively, open any folder and sort by File size (largest first) — that surfaces the biggest space consumers fast.
Common culprits:
- Camera roll backups from your phone (photos and videos add up quickly)
- Duplicate files and old versions of documents
- Large downloads, ZIP files, or video files that ended up in a synced folder
- OneNote notebooks with embedded images, audio, or PDFs
- Outlook email attachments (these count against OneDrive quota on personal accounts, not a separate email limit)
Method 1: Delete Files Directly in OneDrive (Web)
This is the most direct approach and works from any device with a browser.
- Go to onedrive.live.com and sign in
- Browse to the files or folders you want to remove
- Check the box next to each item (or click the circle that appears on hover)
- Click Delete in the toolbar at the top
- Confirm the deletion
To select everything in a folder, click the first item, then hold Shift and click the last — or use Ctrl + A to select all. Then delete in bulk.
Important: deleted files go to the Recycle Bin first. They still count against your storage quota until you empty it. Skip to Method 3 to clear the Recycle Bin after deleting.
Method 2: Delete Files via File Explorer on Windows
If you have the OneDrive app installed on Windows, your OneDrive files appear in File Explorer like regular folders.
- Open File Explorer and click OneDrive in the left sidebar
- Browse to the files you want to remove
- Select them and press Delete (or right-click and choose Delete)
- The files are removed from both your computer and the cloud
A critical thing most people miss: deleting a file from your local OneDrive folder removes it from the cloud too — they’re synced. If you want to keep a file on your computer but remove it from OneDrive, you need to move it out of the OneDrive folder first (drag it to a regular folder like C:\Users\YourName\Documents outside of OneDrive), then delete it from OneDrive.
Method 3: Empty the Recycle Bin (Don’t Skip This)
This is the step that catches almost everyone. After deleting files, your storage gauge won’t move until you empty the Recycle Bin. Deleted files sit there for up to 30 days before being removed automatically.
To empty it immediately:
- In OneDrive web, click Recycle bin in the left sidebar
- Click Empty recycle bin at the top
- Confirm
The space comes back right away. If you just cleared out a bunch of files and your storage bar didn’t change, this is why.
Method 4: Use Files On-Demand to Free Up Local Space Without Deleting
If your hard drive is full but you want to keep files in OneDrive, Files On-Demand is the right move. It keeps files stored in the cloud and only downloads them when you open them — they still show in File Explorer with a cloud icon.
To make specific files or folders online-only:
- In File Explorer, find the file or folder in your OneDrive
- Right-click it
- Select Free up space
The file stays in OneDrive and appears in File Explorer, but the local copy is removed. A white cloud icon indicates online-only status. Double-click anytime to download it again.
To make your entire OneDrive online-only by default:
- Click the OneDrive cloud icon in the system tray (bottom-right of taskbar)
- Click the gear icon → Settings
- Go to Sync and backup → Advanced settings
- Make sure Files On-Demand is turned on
- Then right-click your top-level OneDrive folder in File Explorer and choose Free up space
This is the best option if you’re running low on local disk space but don’t want to delete anything.
Method 5: Stop OneDrive From Backing Up Your Desktop and Documents
Windows often enables automatic backup of your Desktop, Documents, and Pictures folders into OneDrive without making it obvious. If those folders are large, this is likely what’s filling your 5GB.
To stop the backup and reclaim the space:
- Click the OneDrive icon in the taskbar
- Click the gear icon → Settings
- Go to Sync and backup
- Click Manage backup
- Toggle off any folders you don’t want backed up (Desktop, Documents, Pictures)
- Click Save changes
After turning off backup, the files already in OneDrive from those folders remain there until you delete them manually. Turning off backup just stops new files from being added.
Method 6: Find and Delete Large Files Fast
If you just need to free up space quickly and don’t want to dig through folders manually:
On OneDrive web:
- Sign in to onedrive.live.com
- Open My files
- Click the Sort dropdown and select File size (largest first)
- Work through the list and delete what you don’t need
Alternatively: click the gear icon → Options → Manage storage — this shows a visual breakdown of what’s taking the most space.
For photos specifically, check the Photos section. Camera roll backups are one of the most common reasons OneDrive fills up, and duplicate screenshots or low-quality photos are easy to delete in bulk.
Method 7: Clear Old Outlook Email Attachments
If you use Outlook.com (Microsoft’s webmail), large email attachments count against your OneDrive quota on personal accounts — not a separate email limit. This surprises a lot of people.
To check and clear email storage:
- Sign into outlook.com
- Click the gear icon → View all Outlook settings → General → Storage
- Sort by size to find emails with large attachments
- Delete what you don’t need, then empty Deleted Items and Junk Email
After clearing, the space frees up in your OneDrive quota within a few minutes.
How to Check How Much Space You’ve Recovered
After deleting and emptying the Recycle Bin:
- Go to onedrive.live.com/storage — this page shows your current usage in real time
- Or: click the OneDrive icon in the taskbar on Windows — storage usage shows at the bottom of the panel
If storage still shows full after emptying the Recycle Bin, wait a few minutes and refresh. Quota updates aren’t always instant.
OneDrive Storage Plans: When Clearing Isn’t Enough
If you’ve deleted everything you can and still need more space, here’s what Microsoft offers:
| Plan | Storage | Price |
|---|---|---|
| Free | 5 GB | Free |
| OneDrive 100 GB | 100 GB | $1.99/month |
| Microsoft 365 Personal | 1 TB | $6.99/month |
| Microsoft 365 Family | 6 TB (1 TB × 6 people) | $9.99/month |
The 100GB standalone plan is worth considering if you just need more space without paying for Office apps. The Microsoft 365 Personal plan makes more sense if you also use Word, Excel, or Outlook regularly — the 1TB of storage effectively comes with the subscription.
One thing to note: Google Drive gives 15GB free compared to OneDrive’s 5GB. If storage limits are a recurring frustration and you’re not tied to the Microsoft ecosystem, migrating to Google Drive is a legitimate option.
Common Problems and Fixes
Deleted files but storage didn’t change: You forgot to empty the Recycle Bin. Go to OneDrive web, click Recycle bin in the sidebar, and empty it.
Files show in File Explorer but won’t delete: If the file has a sync error (indicated by a red X icon), the local and cloud versions may be out of sync. Right-click the file and choose Always keep on this device first, then delete it.
OneDrive keeps re-uploading files you deleted: Automatic backup is probably still enabled for those folders. Go to Settings → Sync and backup → Manage backup and turn it off.
Can’t see what’s using space: Sign in to OneDrive web and use the Manage storage page under Settings → Options. It shows a breakdown by category including photos, documents, and email attachments.
Phone camera backup filling OneDrive: On the OneDrive mobile app, go to Me (bottom right) → Settings → Camera upload and turn it off. Then delete the Camera Roll folder from OneDrive web if you don’t need what’s already there.
FAQ
Does deleting files from OneDrive delete them from my computer? If the files are synced (shown with a green checkmark in File Explorer), yes — deleting from OneDrive removes them locally too. To keep a local copy, move the file out of the OneDrive folder to a regular location on your computer first, then delete it from OneDrive.
Why is my OneDrive still full after deleting files? Deleted files go to the Recycle Bin and still count against your quota for up to 30 days. Go to OneDrive web, open the Recycle Bin from the left sidebar, and click Empty recycle bin.
What’s the difference between OneDrive and local storage? OneDrive is cloud storage — files are stored on Microsoft’s servers and synced to your device. Local storage is your physical hard drive. Files On-Demand keeps files in the cloud but makes them appear in File Explorer without taking up local space.
How do I stop OneDrive from filling up automatically? Turn off folder backup in OneDrive Settings → Sync and backup → Manage backup. Also disable camera upload in the OneDrive mobile app if you’re on Android or iOS.
Can I permanently delete everything in OneDrive? Yes. In OneDrive web, select all files in My Files and delete them. Then empty the Recycle Bin. This permanently removes everything from cloud storage. Make sure you have copies elsewhere before doing this.
Does OneDrive delete files if I cancel my Microsoft 365 subscription? Yes — if you were on a paid plan and your storage exceeds the free 5GB tier when your subscription ends, Microsoft locks your account from uploading new files. Files remain accessible for 30 days after downgrade, then are deleted if you remain over the free limit. Download anything you need before canceling.
How do I free up local disk space without deleting OneDrive files? Use Files On-Demand. Right-click any file or folder in your OneDrive in File Explorer and select Free up space. The file stays in the cloud and appears in File Explorer, but the local copy is removed.
What counts toward OneDrive storage? Files in your OneDrive, your Recycle Bin contents, and Outlook email attachments (on personal accounts) all count. Files shared with you by others do not count against your quota.
