Exploring the created Snapshot disk image is extremely simple and powerful : use the normal Windows explorer - or any other program you like. Snapshot achieves this by creating a virtual drive - like W: - usable by any Windows program. This virtual drive can be used by the normal Windows Explorer. Here are Screenshots how to view a saved disk image. Main use: You can view/compare files without restoring them first. First you have to select the disk image you want to explore. You see some information about the saved disk at the time of Backup to help you to find the right image, should there be more than one. Additionally, you may choose the drive letter the virtual drive shall have; Drive Snapshot will automatically use the highest drive letter available (Z:). Click Map and Explore Virtual Drive to mount the drive and start the Windows Explorer on the drive. Click Map Virtual Drive to mount the drive only without starting Windows Explorer. Partial Restore You can do a partial Restore, simply by dragging and dropping files with Windows Explorer. And, since it's a virtual drive, the image can be used by any other Windows/DOS program, not just an 'explorer like' browser. Simply use the tools you like most to view/compare/restore files. When viewing a saved NTFS partition, the virtual drive will have exactly the same security attributes, owner ship, compressed state, encrypted state,... as the original disk. Performance Snapshot virtual disk has performance similar to a real disk. Depending on the conditions, expect 50-120% of the speed of the real disk (yes, sometimes it's faster:-). For instance, Win2K backup will back up my Win2K System disk in 7:43; while saving the same drive as a virtual disk takes 10:28, or about 35% slower. Most important - it will never feel slow.
