mTCP NetDrive lets you mount floppy disk and hard drive images over the network to your DOS machine, allowing you to add gigabytes of network attached storage in seconds. It runs on all versions of DOS starting at DOS 2.0, requires a minimal amount of RAM, and will work across WiFi or even across the Internet.

The newest version has a big new feature - "Undo" support for hard drives. Imagine being able to undo accidents, corruption, or just revert your drive images to an earlier state in seconds, right from inside of DOS. This version of NetDrive does that, with no additional memory requirements on the DOS side. Enabling this feature is as simple as creating a zero length file on the server side. The best way to understand it is to try it out:

• Setup journaling on a disk image - create the a zero length file on the server side for the disk image you want to add "Undo" to.
• Connect to the disk image from DOS
• From inside of DOS use the "NETDRIVE LIST_CP" command to ensure journaling is actually enabled on the image.
• Make a mess ... delete things, cross link the FAT, whatever you want.
• From inside of DOS use the "NETDRIVE GOTO_CP" command, and within a few seconds you are back to where you were when you first started.

Other changes include support for longer drive image names, better error handling when a UDP packet is lost, and some minor performance improvements.
