CCleaner (Crap Cleaner) is a freeware system optimization tool that removes unused and temporary files from your system, allowing Windows to run faster, more efficiently and giving you more hard disk space.The best part is that it's fast! (normally taking less that a second to run) and Free.

CryptoExpert creates encrypted virtual disks and these disks are visible as usual disks with drive letters (for example, G:, H:, Z:, i.e. with any drive letter that is not used by other system devices). The data stored on a CryptoExpert disk is stored in the container file. A container is a file, so it is possible to backup a container, move or copy it to other disk (CD-ROM or network, for instance) and continue to access your encrypted data using CryptoExpert.
