@Androdion So the answer is, according to someone who knows about it apparently :
< It means that the temporary files the system itself (Windows 10 OS) creates in some cases (not all) will be deleted.
So, whatever this software is, if it is creating its own temp files - Microsoft/Windows could care less and actually doesn't even know they are actually temporary files and will not touch them.>
[Edit: Apparently, the said expert wasn't one, and such files aren't deleted]
So no reason to blame windows for this, no worry though, as the only inconvenience is kill the process twice before being able to tun it, I'll do it ^^
@Hooyaah À la bonne votre!! Cheers mate! “All we have to decide is what to do with the time that is given us.” I'm glad you've decided to help others with the said time ^^
