Microsoft included a feature called Virtual DOS Machine (VDM) to allow users to run legacy DOS-based applications within Windows. The document then lists and describes various basic DOS commands that can be executed from the Windows command prompt, such as DIR to display files in a directory, MD to create a new folder, CD to open a folder, and DEL to delete a file. It provides details on over 30 common DOS commands for navigating, viewing, copying, moving, deleting, and managing files and folders from the command line interface.
