Cache stores recently used information so that it can be accessed again with increased speed. When the same operation is made again, the corresponding cache will be read and the task will be completed in less time.
Since cache stores data transparently, users have no control over its contents, but they can adjust its size to make sure it does not take up too much space.
Cache cleaners will erase all the stored data and will free hard disk space.
These applications will also help users to maintain their privacy on computers shared by several persons.
