Caching Location and Free Space

[VasilisPat]

Noticed C: free space getting to low because of cached videos stored into it ,so I changed it to D:

After letting the screensaver run for a bit I noticed the space on th C: drive dropping low again. Checked the new cache folder on D: for videos, all ok new videos have been added. Performed a restart on the computer, C: free space gone back to normal(this solution doesn't apply on shutdown due to fast Startup option on Windows 10).

I let the screensaver run again, checked th C: drive again, space has decreased by ~1.2Gb. Checked new caching location on D: also gets larger alongside. Decided to run the Windows Disk Cleanup Tool, free space returned to normal. Also performed a check with some disk space analyzer tools, can't find anything related to .mov files.

This problem only occurs when I run the screensaver, so no other app appears to be responsible for this issue.
