Although this was suggested a year ago its still not included in CCleaner. I assumed that recent items were being cleared in Vista, but was surprised to come across this folder bulging with zillions of tiny shortcut files. Apart from anything else its a very easy way for people to track your useage.
The folders that I have added manually are as follows:
Include1=PATH|C:\Users\Liam\AppData\Roaming\Microsoft\Windows\Recent\|*.* (mentioned above)
Include9=PATH|C:\Users\Liam\AppData\Local\Microsoft\Media Player\Art Cache\|*.*
Include12=PATH|C:\Users\Liam\AppData\Local\Microsoft\Windows Mail\Local Folders\Junk E-mail\|*.*
Some of these are Vista, some are common applications and some just stuff I use.
(*) PLEASE NOTE - My user name is LIAM so you must be careful to replace that with yours (and do it accurately) This is a single user machine, if yours is not then the matter is more complex.
I wonder if some of the more common ones, like AVG, and the windows stuff could be included? Anyone can edit their CCleaner.ini file to add these folders so I have kept the format, but make sure you change the Include number to avoid duplication in your ini file.
I think they are all safe, of course there's no point trying to clean folders that don't exist on your machine.
(*)Don't add the windows mail one if you use that programme regularly because you run the risk of losing legit emails that have wrongly been junked.
(*) The WMP art cache folder was full of crap I never use (I avoid WMP whenever possible) so if you are a WMP fan and use whatever art features may happen to be then don't include that folder.
(*) Kontiki - This file sharing app is installed by the BBC iPlayer download manager and the Channel 4 4od manager (only of interest to UK users) and probably other applications (look at Wikipedia to find out). My advice is stay away from Kontiki altogether, its a bloody nightmare. Its next to impossible to uninstall, it hogs your bandwidth and it builds up ginormous logs and temp files.
Hope this helps someone
