Snapper 2 - Version 2.79 Quickly take a Snapshot of a directory, hard-disk or network volume, and retrieve it at a later date for wysiwyg comparison of file size, date/time, flags, and internal version, with a second Snapshot. The two Snapshots look like Explorer windows but they scroll in sync to instantly show you the differences. Open some more Snapshots and they scroll along with the others. Never before has it been so quick and easy to visualise directory changes!
