PowerMerge is File Synchronization and Online Backup software for Macintosh computers. Whether you are synchronizing files between a PowerBook and a desktop Mac, backing up data online to a second hard drive, moving files between the home and office, or updating multiple computers on a network, PowerMerge reliably and securely updates and synchronizes an unlimited number of files, folders and disks. Simply select which Macs or disks you want to keep up to date, and PowerMerge does the rest. It scans each computer's disks and determines if changes have been made to existing files, recognizes if files have been relocated, renamed or deleted on each Mac, and automatically updates and moves files on each Mac if necessary. It's like having your own personal file clerk to monitor and update all the Macs and disks you work on. PowerMerge is used by virtually every large Macintosh organization and is the highest rated file synchronization program on the market today. NOTE: PowerMerge is not an OS X native program. It only runs in Classic mode. Please see the FAQ on this subject.
