I've been going through my phone and deleting old stuff, but trying to open some files it tells me there's not enough space on the disk (the SDD), all the whilst noticing the free space go lower and lower. So I've been copying it over to my other hard drive and having to watch it there.
I've restarted the system thinking it would clear the cache or whatever but it doesn't seem to have done anything, and there's nothing standing out in the C: > Temp folder.
On the same vein I have some things I'm not sure if I can delete safely, namely the second Program Files folder, named Program Files (x86) and the Windows.old folder. Can I delete them without compromising the other systems?
