Deltree
From Wikipedia, the free encyclopedia
Deltree (short for delete tree) is an operating system command in Microsoft operating systems that deletes an entire subdirectory of files. It appeared in MS-DOS 6, and was retained throughout all Windows versions based upon MS-DOS, including Windows 95, Windows 98, and Windows Me. (For Windows versions before Windows 95, the presence of Deltree depended on the version of the MS-DOS that was already required to be on the machine, which was completely separate from Windows.)
Deltree isn't present in Windows NT-based operating systems, including Windows NT, Windows 2000, Windows XP, Windows Server, or Windows Vista. Instead, the rd or rmdir (remove directory) command removes a subdirectory along with all its files if the /s command line switch is present.
