SSSynchro - Version 1.3 The main field of application of SSSynchro is packing and management of different versions of large-size documents such as Corel Draw! drawings and backups, AutoCad projects and backups, Pro-Engineering projects and backups and many others as well as large (more than 200 KB) updateable text documents in *.doc, *.txt, *.rtf . It allows you to create as many archives as you like and browse for files to drag and drop into those archives. You can also drag and drop files from Explorer right into the archives. The archives can handle very large files, and can contain multiple versions of the same file. Files added to SSSynchro archives are simply copied -- original files remain intact on your hard drive.
