how to work with DOS

Many DOS command examples are listed under "DOS" in the index; for example, DOS Copy, DOS Format, etc. For a complete tutorial on how DOS disks are organized and how you interact with DOS at the command line, see DOS abc's. Most DOS commands are still valid in Windows, and you can execute single commands or create batch files for automating routine procedures (see DOS batch file). Except for the desktop, which did not exist in DOS, the DOS and Windows file system hierarchy is almost the same.
