How to free or clean up disk space on windows 10?
My primary drive (C:) is running very low on space, which is causing slowdowns. I've already deleted my own personal files that I don't need. I'm familiar with the basic "Disk Cleanup" tool and have ...
The hibernation function of Windows system generates a file named hiberfil.sys, which occupies a disk space equal to the memory capacity of your computer. If you usually only use the shutdown or sleep function, and don't use hibernation, you can safely disable hibernation to free up this part of the storage space.
- Search for cmd, right-click Command Prompt, and select Run as administrator.
- Type: powercfg.exe /hibernate off and press Enter.
- After execution, the system will delete the hiberfil.sys file immediately to clean up disk space on Windows 10
By following the above steps, you can safely and efficiently reclaim space on your C drive, thus solving the computer slowdown problem caused by excessive disk space occupied by the system.
