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 Windows 10 update. What is more, then are a lot of important configuration files saved in C drive and nothing to delete when the C drive is full.
I want to know if there is any safe way to extend C drive when C drive is full in Windows 10 PC without losing data?
Best Regards,

I 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.

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.
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!
- Honestly, 60GB of C drive is not enough for running Windows 10 smoothly. One simple trick to fix C drive full issue is by using the default disk cleanup utility to delete the old Windows 10 OS backup file. However, the c drive will be full when a new Windows 10 update is available for installation.
