Tirum: "... c:\temp ... is not the default folder in Windows and usually no folder with this path, only you have it created and set manually"
"to you mean c:\windows\temp?"
mta: " I change my USER and SYSTEM %temp% and %tmp% variables and CC cleans them fine."
" untick those 24 hour boxes to allow CC to clean more recent files. "
I only want the older files deleted. There are .tmp files in both places from 2016 -- they remain.
"for the two %temp% and %tmp% folders, CC will remove all contents regardless, for other folders it only removes files that meet its criteria; like tmp, log, wer files etc.
so your %temp% files probably have stuff left because your 24 hours box is ticked.
and your original %temp% folder (c:\users\xxx\appdata\local\temp) still has contents because, despite the name, it is now just a 'normal' folder and will only get cleansed for those file type that trigger CC's rules."
At may now be a normal folder, but it is a common Windows "temp" folder, which, actually (based on the dates), some programs still use!
I think these are things that might make CCleaner better.
Thank you all for your interest.
