MD

Make Directory - Create a new folder/directory.

Syntax
      MD [drive:]path [[drive:]path...]

Key
   path  The path/directory to create.

The path can consist of any valid characters up to the maximum path length. Command extensions, which are enabled by default, allow a single MD command to create all the intermediate directories in a specified path.

Directories are one type of folder, namely, folders which correspond to file system locations. There are other types of folders, such as Control Panel or Network Neighborhood or Printers. These other types of folders represent objects in the shell namespace which do not correspond to files.

Naming Restrictions

The set of CMD delimiters (Comma , Semicolon ; Equals = Space ' ' Tab '   ') can be used in a folder name, but they must be enclosed in quotation marks:
MD "aa=bb" will create a folder called 'aa=bb',
MD aa=bb will create two folders 'aa' and 'bb'

Try to avoid using the following characters in folder names, they may cause problems when scripting: © ® " & ' ^ @

The maximum length of a full pathname (folders + filename) is 260 characters, this is a limitation of Windows Explorer not NTFS.

You cannot create a folder with the same name as any of the following devices:
CON, PRN, LPT1, LPT2 ..LPT9, COM1, COM2 ..COM9
This limitation ensures that redirection to these devices will always work.

Errorlevels

If the Directory was successfully created %ERRORLEVEL% = 0
If the Directory could not be created %ERRORLEVEL% = 1

MKDIR is a synonym for MD

Examples

C:\temp> MD MyFolder

Make several directories with one command:

C:\temp> MD Alpha Beta Gamma

will create

C:\temp\Alpha\
C:\temp\Beta\
C:\temp\Gamma\

Make an entire path
MD creates any intermediate directories in the path, if needed.
For example, assuming utils does not exist then:

 MD utils\downloads\Editor 
   
   is the same as: 
   
   MD utils 
   MD utils\downloads 
   MD utils\downloads\Editor

for filenames with spaces or punctuation characters, add surrounding quotes:

 MD "\utils\downloads\Super New Editor"
