As applications continue to be installed into the Windows system, one day, suddenly you will find that the system (drive C:) or boot partition do not have enough free disk space, and when every time the system starts, Windows always prompts the following information:
"You are running out of disk space on SYSTEM (C:), To free space on this drive by deleting old or unnecessary files, click here…"
In this case we have two solutions:
Solution A- Delete the unwanted files for getting more free space like what system suggests. However, deleting files is not the best way, it could not solve the issue from the roots.
Solution B- Addressed the issue from the roots, extend system partition size by using Windows partition manager (AOMEI Partition Assistant or Disk Management) to allocate free space from other partition to system drive. Here is an example about the "solution B", the demo partition configuration is lay out as below:
