Synchronize! X Plus is a personal file synchronization and backup utility. It has been re-engineered for OS X, taking advantage of the modern properties of the operating system, such as preemptive multitasking, and supporting the full capabilities of the file system, including 255-character Unicode file names and OS X file permissions. Files are copied at the maximum speed possible, using preemptive multitasking to full advantage.
