From JLO Management:

WinSync is a software tool for managing the directories and files of Windows and namely: comparison of directories or files, without any limitation in size and at any location on your computer or the computers connected through a local network. Identification of missing directories, missing files and files having the same names but of different content. Synchronization of the contents of two directories with several options. Making identical two files having the same name by choosing a reference. Searching for doubles and possibly eliminate them. Creating empty files or directories. Deleting files or repertories. Sanitization of the space occupied by files or the whole free space of disks by using the Gutmann algorithm performing on any magnetic media. Ciphering and deciphering files and possibly signing them by using specific keys or pairs of public/private keys and generating those keys. Searching for all files incorporating a given string of characters and whose name satisfies the specifications of a mask. Archiving and restoring a directory.
