Hello, I have a small trouble with ccleaner. I brought the professional version, has the last update install. When i launch a full clean it don't remove all deleted files from the bin. After some time, i realize that the files that are not clean, all comes from my NAS (connected through a mapped network drive X:) I don't find any options to force ccleaner to clean all the bin. Do you have any idea how to do this ? Thank you for you help.
