SnapShot - DiskImage Explore

Test the Snapshot Userinterface
Exploring the created Snapshot disk image is extremely simple and powerful : use the normal Windows explorer - or any other program you like.

To do that, Snapshot creates 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 points: You can view/compare files without restoring them first.

Partial Restore

You can do a partial Restore, simply by dragging and dropping files with Windows Explorer.
And, since it's a virtual drive, not just an 'explorer like' browser, the image can be used by any other Windows/DOS program. Simply use the tools you like most to view/compare/restore files.
When viewing a saved NTFS partition, the virtual drive will have exact the same security attributes, owner ship, compressed state, encrypted state,... as the original disk.

Performance

Snapshot virtual disk has a performance similar to the real disk.
Depending on the test, expect 50-120% of the speed of the real disk (yes, sometimes it's faster:-). For instance, Win2K backup will backup my Win2K Systemdisk in 7:43; saving the same drive as virtual disk takes 10:28 or about 35% slower.

Most important - it will never feel slow.

What might be done

Currently, the created virtual drive is read only, so it can't be modified.
As the device driver sees any write attempt to the drive, it would be possible, to make it writeable as well and store all modified data into a separate delta file.
