  Striclone is useful for hard drive clean up from duplicate files and thus freeing up space on the drive. Having image of the hard drive, user can promptly monitor and swiftly manage new duplicates on the drive.
Striclone saves not only space on your hard drives; it also saves time on the drive clean up process. The program's new feature - use of drives' images - can considerably speed up the search process.
Image of drive is a special file, which stores information on files and folders located on drive. That information includes files and folders names, their size, date they were created and the files' so-called CRC (cycling redundancy check sum). The CRC sum is often used to uniquely identify a file. Striclone uses image of drive for speeding up the duplicate search. It creates the image only once and uses it multiple times instead of reloading the files' properties off the hard drive over each time. When a content of the drive changes, user may update the image of drive. Since it adopts only the updated information, the procedure runs very quickly.
