Hey!
thanks a lot for your answer.
Perhaps we speak about different things? In the PortableApps.com scheme, the folder with all the apps is (not hidden, and is):
T:\PortableApps
e.g
T:\PortableApps\FirefoxPortable
T:\PortableApps\OperaPortable
T:\PortableApps\ThunderbirdPortable
etc.
and most cached files are not in C:\temp or C:\windows\temp, but below those folders named above inside \Data\, e.g.
T:\PortableApps\ThunderbirdPortable\Data\profile
The idea (of my feature request) is actually not needing to "know what to clean" but ...
... offer a scanner, which scans
T:\PortableApps\
and then maps the results (a list of all installed portableApps) to the already known CCleaner knowledge about those apps.
So that their cleaning can be automated. Perhaps in a separate tab, like CCleaner --> Cleaner --> [Windows, Applications, PortableApps].
I think that feature request would greatly improve the scope of this -already fantastic- tool CCleaner.
Thanks for considering it. Happy to answer any questions.
Andreas
