1Disk - Version 2.0 A file system management and organization tool for Windows. 1Disk looks like just another disk drive to Windows and works like an ordinary disk drive as well, but with a twist. 1Disk keeps track of the contents of all your Zip disks, Jaz disks, floppy disks, removable disks, and CD-R disks, whether the disk is in its drive or not. 1Disk makes it possible for you to organize and access all of your files, regardless of where they are stored!
