Why is C drive running out of space in Windows 11 computer
In most of Windows 11 laptop/desktop/tablet, it becauses that C drive is filling up. All programs are installed to C: drive by default and many people did this. The more programs you installed, the less free space left. In addition, games and some other programs are very large and they'll output big files.
Besides programs installation and output, Windows itself will generate many types and large amount of files such as cache, temporary, download, Recycle Bin. The longer you run this computer, the more junk files are saved in C: drive.
If you enabled system protection, hibernation and other services, very larger file will be saved in C drive, too.
What to do when C drive runs out of space in Windows 11
When C drive is running out of space in Windows 11 computer, the first thing you should do is cleaning up C drive to remove junk and unnecessary files. The same with previous versions, Windows 11 has native Disk Cleanup tool to help free up disk space on C drive. This native tool is easy to use, fast and safe to delete junk files.
How to clean up disk when C drive is full in Windows 11 laptop/desktop/tablet:
- Press Windows and R keys together, type cleanmgr and press Enter, select C: drive in next window.

Additional steps to fix Windows 11 C drive out of space issue:
- Move installed apps and games out from C drive.
- Change the output path to other large partition.
- Set Paging file to other partition instead of C drive.
- Decrease the space usage for Recycle Bin and System protection.
The steps above are enough to help reclaim disk space in C drive. Of course there are other methods such as searching for similar files and then delete part of them. I do not suggest running this type of tools. If you created C drive too small or if you cannot get over 20GB free space in C drive, the best solution is moving free space to C drive from other partition.
