We have all come across blocked files, or tried to delete and received the news that it is "in use" and can`t be deleted. To avoid this irritating situation, you need Pocket Killbox, a simple program that unblocks these files and deletes them the next time the PC is swithced on. It is enough to select the file you want deleting, and select "delete on restart."
With Pocket Killbox you can also clean your hard drive of temporary files, or end active processes.
