Running low on storage can make your PC feel slower, prevent updates from installing, and force you to constantly delete files just to make room.
The problem is most of your space is being taken up by temporary files, unused apps, and system junk that builds up over time.
The good news is you can clean up a surprising amount of space in just a few minutes using tools already built into Windows 11.
Here are 8 simple, effective ways to free up disk space on Windows 11. If your whole computer feels sluggish, freeing up storage is also one of the easiest ways to help speed up a slow computer.
1. Use Storage Settings (Start Here)
The easiest place to start is the built-in Storage tool.
To open it:
- Click Start → Settings
- Go to System → Storage
This screen shows exactly what’s using space, including apps, temporary files, system files, and more. If you only want to see how much space is available before deleting anything, start with our guide on how to check your storage space on Windows 11.
If you don’t see the full breakdown, click “Show more categories” to expand everything.
Look for:
- Large apps or programs
- Temporary files
- Anything unexpectedly using a lot of storage
From here, you can click into each category to remove files or uninstall apps.

2. Turn On Storage Sense (Automatic Cleanup)
If you want Windows to handle cleanup for you, turn on Storage Sense. It automatically removes temporary files and clears out your recycle bin so junk doesn’t pile up again.
How to enable it:
- Go to Settings → System → Storage
- Toggle Storage Sense ON
- Click into it to adjust settings
Recommended settings:
- Run Storage Sense: During low free disk space (default)
- Recycle Bin: 30 days (default)
- Downloads folder: Leave as Never (safer)
These settings are a good balance for most users and don’t risk deleting anything important from the Downloads folder.

3. Delete Temporary Files
Temporary files can take up several gigabytes and serve no real purpose once they’re created.
How to remove them:
- Go to Settings → System → Storage
- Click Temporary files
- Select the files you want to delete
- Click Remove files
This is one of the fastest ways to instantly free up space.

4. Uninstall Apps You Don’t Use
Unused apps like large programs and games can surprisingly take up a large amount of disk space at times. For a full walkthrough, see our guide on how to uninstall programs on Windows 11.
To uninstall them:
- Go to Settings → Apps → Installed apps
- Sort by Size
- Remove anything you don’t need
Focus on:
- Old games
- Unused software
- Trial programs

5. Empty the Recycle Bin
Deleted files aren’t actually gone until you empty the Recycle Bin.
To clear it:
- Right-click the Recycle Bin
- Click Empty Recycle Bin
If you haven’t done this in a while, it can free up a surprising amount of space.
6. Move Files to External Storage or Cloud
If you have large files like videos, photos, or backups, consider moving them off your main drive.
Options:
- External hard drive
- USB drive
- Cloud storage (like Google Drive or OneDrive)
This keeps your PC fast without deleting important files.
7. Delete Large Files Manually
Sometimes a few large files are the main problem.
Quick way to find them:
- Open File Explorer
- Search for:
size:>1GB
Delete anything you no longer need.
Be careful not to remove important system or program files. If your drive still seems unusually full or your computer is acting slow, it may also be worth learning how to check hard drive health on Windows 11.
8. Disable Hibernation (Advanced)
Windows reserves several gigabytes for hibernation—even if you never use it.
Disabling it can instantly free up space.
How to disable it:
- Open Command Prompt (Admin)
- Run this command:
powercfg -h off
Only do this if you don’t use hibernate mode.
Final Thoughts
Running out of disk space on Windows 11 is common, but it can also be easy to fix.
Start with Storage Settings, clear out temporary files, and remove anything you don’t need. If you go through these steps, you can free up a significant amount of space without touching your important files.
