C drive is full. How can I extend C drive without losing data on Windows 10 PC?
 Hi all,     I have a old Windows 10 PC with only 128 GB SSD. I did a mistake when partitioning the drive. The C drive only has 60GB space and C drive is always full, especially after installing a new...
- Sep 05, 2025I ran into the same 60 GB C: squeeze and used Dr.Partition to shrink the next partition and extend C: on the fly—no data loss. Super simple wizard, one reboot to apply, and my files/settings were all still there after. https://www.uuwinfox.com/extend-c-drive Highly recommended!

C drive full? First things first, let's hit up the built-in Disk Cleanup tool. This bad boy can sift through your system and find a ton of stuff you can safely toss:
- Open Disk Cleanup: Just search for “Disk Cleanup” in the Start menu. Select your C drive when prompted.
- Choose What to Clean: It’ll scan and give you a checklist. You’ll see stuff like “Temporary Files,” “Recycle Bin,” and “Thumbnails.” Check the boxes for what you want to delete. If you see “Windows Update Cleanup” in there, that can reclaim a good chunk of space too.
- Run It: Press “OK,” and it’ll do its thing.
