Why Upgrade to PowerMerge 2.5? If you have a version of PowerMerge prior to version 2.5 (including PowerMerge Limited Edition), here is why you should consider an upgrade: The full version of PowerMerge provides the following added features and benefits: Files that are renamed, deleted or relocated on one Mac or disk, are automatically renamed, deleted and relocated on the other Mac or disk. When a file is changed on both Macs before you have a chance to update, both versions are saved so you don't inadvertently overwrite one version. Viewing filters allow you to locate all duplicate files on the Macs being compared to free up valuable disk space; see all files from all folders that will be affected in a single view; and sort all files by name, date, size, and kind. Documents and folders can be opened directly from the PowerMerge window. Folders can be deleted from the PowerMerge window. Two versions of the same small (<32K) TEXT document can be compared on a line by line basis, and blocks of text can be moved from one to the other. Great for programmers! Files can be forced to move in a chosen direction. A PowerMerge manual is included with the upgrade. Scheduling, automatic backup on disk insertion and much, much more! This upgrade comes with a complete 30 day money back guarentee. If you are not completely satisfied, simply send it back for a full refund. CLICK HERE TO FIND OUT HOW TO UPGRADE!
