I recently built a new computer and installed Windows 10 Home and ideally I would have had the following: Operating System (C), Games (D) and Everything Else (G) - C and D on my SSD and G on my HDD. However, after the install, a disk 'F' appeared on my SSD and has the same or similar folders as my 'C' drive, and I don't know why. From some searching this would appear to be normal and unavoidable, however, other people's 'F' disk only seems to take up a few hundred Mb's while mine has a capacity of nearly 20Gb. Why is this file here, why are certain programs e.g. Movavi Video Suite defaulting to it for photo/video saves and can I get rid of it and return the 20Gb back to C or D disk? Thanks, Tom.
