MS-DOS Commands :: md (mkdir)
Creates a directory.
The command mkdir is the same as the md command; they do the same thing. You can use either the mkdir command or use the md command which takes fewer characters to type.
Creates a directory. MKDIR [drive:]path MD [drive:]path If Command Extensions are enabled MKDIR changes as follows: MKDIR creates any intermediate directories in the path, if needed. For example, assume \a does not exist then: mkdir \a\b\c\d is the same as: mkdir \a chdir \a mkdir b chdir b mkdir c chdir c mkdir d which is what you would have to type if extensions were disabled.
