How to Resize Partitions on Windows 11/10/8/7 Without Data Loss

"I have two hard drives, C and D, with a total of 2 TB storage space. Frequently, I receive warnings that my C drive (currently allocated 118 GB) is running out of space. Hence, I attempted to shrink D drive (with 1.4 TB of available space) to extend C. The shrinking process was successful. However, when I tried to reallocate the freed space to expand C, the 'Extend' command was disabled, and I couldn't extend the C drive. Did I miss any steps in the reallocation process? Has anyone encountered a similar issue? If so, could you share how you resolved it?"

Why does my computer keep showing insufficient disk space?

If you're getting an "Out of disk space" error, it's because the Temp folder is full. If you free up space on your device using Disk Cleanup, and still get the "Out of disk space" error, it's possible that app files used by the Microsoft Store quickly fill up the Temp folder.

Why is the C drive full in Windows 10?

Generally, your hard drive might not have enough space to store massive data. Besides, if you're only bothered by the C drive being full, there could be too many apps or files saved on it.
