"A free tool to delete temporary files, cookies, traces of uninstalled files, etc."
Uninstall Master is a small, free tool that works to delete temporary files, cookies, registry traces, forms used but which are now useless, etc that only take up space on your hard drive. Uninstall Master is efficient and deletes everything that is useless (but you need to be careful not to delete anything useful), including files that other, similar programs wouldn`t delete.
It also deletes traces of your Internet browsing, and of programs that have been uninstalled. The weak point of the program is its interface, which isn`t very intuitive.
As for everything else, it is worth downloading.
