Dylanopen If your C drive is full on Windows 10, here are some steps to free up space:
- Go to File Explorer, right-click the C drive, and select Properties.
- Click Disk Cleanup and choose the file types to delete, like temporary files, system cache, or recycle bin contents.
- Select Clean up system files for more options, including Windows update cleanup.
This is very easy way to fix C drive is full in Windows 10 by emptying free space. You don't need to install any software to extend C drive in such a case!
