I am struggling for a while with the problem, my computer running out from space time-to-time. I didn't see anything on the Storage analysis of Windows 10 but the "System and Reserved files" is over 250-300 GB.
Every time if I restart my computer, this size is reduced back to normal 25 - 30 GB.
The computer is used for development, usually running all the time (without restart) but now running out of space in one day.
Yesterday I installed the WizTree (earlier I used WinDirStat what was not able to show what eating my space) and got the result the $Extend hidden folder is using 294GB from the 500GB.
Any idea what could cause this?
