When the DOSBox application is opened, it automatically mounts to a virtual, permanent [24] Z: drive that stores DOSBox commands and utilities. [28] The reasons for the virtual drive are related to security, [ 29 ] but the user can mount a different drive letter in the emulator to a directory, image file, floppy disk drive, or CD-ROM drive on ...
HDCopy is a disk image application for floppy disks that runs in MS-DOS.It can copy a floppy on the fly, or by using archives with IMG file extension that store the content of the disk with a proprietary file format (whose first three bytes noted in hexadecimal will be FF 18, and its size will be anything [clarify]).
VGA-Copy was popular because it could often read floppy disks with errors. It does so by automatically doing multiple read retries on errors. Furthermore, VGA-Copy can read floppy images and saves them with the extension .vcp as a 1:1 raw copy of the floppy disk without special headers and formats.
Mtools is an open source collection of utilities to allow a Unix operating system to manipulate files on an MS-DOS file system, typically a floppy disk or floppy disk image. [2] [3] The mtools are part of the GNU Project and are released under the GNU General Public License (GPL-3.0-or-later).
The Professor SF is a backup device for the Super Famicom and allows for saving games to floppy disks. A game backup device, informally called a copier, is a device for backing up ROM data from a video game cartridge to a computer file called a ROM image and playing them back on the official hardware.

Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions).
MSX-DOS and the extended BASIC with 3½-inch floppy disk support were simultaneously developed by Microsoft and ASCII Corporation as a software and hardware standard for the MSX home computer standard, to add disk capabilities to BASIC and to give the system a cheaper software medium than Memory Cartridges, and a more powerful storage system than cassette tape.
