clonemaster will clean your hard drive of duplicate files that are just wasting space. clonemaster searches for true duplicate files (byte for byte). it does not find duplicates by filename, date, size or crc. it does so by comparing the file data itself ensuring 100% accuracy. clonemaster uses a special algorithm that makes the scan extremely fast. it is as fast as your drives can deliver. clonemaster let you find duplicates in multiple paths, backups drive, drives (hard drive, floppy, usb stick, jaz, zip, cdrom, dvd, network drives, etc.). clonemaster can scan files with size over 2gb. 32bit is something of the past, clonemaster handles 64bit file size. all of the duplicate files are listed in a single list to quickly select those to delete. using the header sort and the "mark all but first" button, you can easily select the old duplicates to delete. not only can clonemaster find duplicate files, but it also find zero length file (empty files) and empty folders. the system context menu (using the right mouse click) allow you to preview files, view the properties, delete etc. clonemaster allows you to disable or enable the hidden files and folders before you start a scan. clonemaster is a multi-language (unicode) interface, create your own language by editing the language file directly.
