CleanUp is an application whose main goal is to eradicate any temporary file in your HD.
CleanUp will scan the recycled bin, temporary files folder, history and internet temporary files and will delete the files from them, so your HD will have more space.
It can be used also if you want to delete the tracks you leave when surfing the net because it will leave no traces of your surfing actions.
CleanUp can use four different ways of cleaning: basic, normal, full or custom. The space optimized will vary depending on the kind of scan and the time since you did the last cleaning.
