Make Directory - Creates a new folder.

Syntax
      MD [drive:]path

Key
   The path can consist of any valid characters up to the maximum path length available

You should avoid using the following characters in folder names - they are known to cause problems

© ® " - & ' ^ ( ) and @

also many extended characters may not be recognised by older 16 bit windows applications.

The maximum length of a full pathname (folders and filename) under NTFS or FAT is 260 characters.

Folder names are not case sensitive, but only folder names longer than 8 characters will always retain their case, as typed.

For Example

C:\temp> MD MyFolder

Make several folders 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 
   cd \utils 
   md downloads 
   cd downloads 
   md Editor 

for long filenames include quotes

MD "\utils\downloads\Super New Editor" 

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.

If you plan to copy data onto CDROM avoid folder trees more than 8 folders deep
