A disk operating system (DOS) is a computer operating system that resides on and can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc.A disk operating system provides a file system for organizing, reading, and writing files on the storage disk, and a means for loading and running programs stored on that disk.
Digital Research DR DOS 6.0 [16] and Datalight ROM-DOS [17] also include an implementation of the diskcopy command. The FreeDOS version was developed by Imre Leber and is licensed under the GNU GPL 2. [18] The command is not included in Windows 10. [19] [failed verification] The command is not included in Windows 11. xcopy is a like command
Apple DOS is the disk operating system for the Apple II computers from late 1978 through early 1983. It was superseded by ProDOS in 1983. Apple DOS has three major releases: DOS 3.1, DOS 3.2, and DOS 3.3; [2] each one of these three releases was followed by a second, minor "bug-fix" release, but only in the case of Apple DOS 3.2 did that minor release receive its own version number, Apple DOS ...
The first sector of DOS-formatted diskettes is the boot record. Two copies of the File Allocation Table occupy the two sectors which follow the boot record. Sectors four through seven hold the root directory. The remaining 313 sectors (160,256 bytes) store the data contents of files.
The version included with PC DOS 3.0 and 3.1 is hard-coded to transfer the operating system from A: to B:, while from PC DOS 3.2 onward you can specify the source and destination, and can be used to install DOS to the harddisk. The version included with MS-DOS 4 and PC DOS 4 is no longer a simple command-line utility, but a full-fledged installer.
Users could press a key to indicate what they wanted to happen; available options included: [3] Abort (A): Terminate the operation or program, and return to the command prompt. The program would not do any cleanup (such as completing writing of other files). Retry (R): Attempt the operation again. "Retry" was what the user did if they could fix ...
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.

A direct descendant of OS/A+, DOS XL provided additional features to Atari's equipped with floppy disk drives. These included single and double density support, a command-line mode (called the command processor or CP), a menu mode (an executable loaded in memory), batch file support, and support for XL extended memory and OSS SuperCartridge banked memory.
