Months ago, not recently.
I simply ran the default diskcleanup, so I am sorry I don't know what it's settings were. And after reading Make Disk Cleanup More Powerful I have this evening altered settings away from the default.
I certainly don't use compress old files.
Old Win or WinOld (whatever it was called) went long ago.
Office Install: If it were there, I was ignorant of it. Office 2003 is on D:
Downloaded Programs folder: Possibly.
Sorry, don't understand how this relates to my situation.
Would it be worthwhile having an option in CCleaner to tell the user what could be saved if different options were selected?
I have been ignorant of what was accumulating ... and, frustratingly, still don't know what diskcleanup removed.
It was only a fair bit of digging with DiskPiePro in response to a free space crisis that made me aware of the old downloads, the old Lenovo stuff etc.
