Switches can be pre-set in the DIRCMD environment variable. By adding a prefix - (Dash)
to replace the pre-set switch. For example, /-W.

Using the /D command line switch, in addition to changing the current directory of the drive,
You can also change the current drive.
If the extension command name is enabled, CHDIR changes as follows:
The current directory string is converted to use case on the disk name. So
If this is the case on the disk, CD C: s TEMP sets the current directory to
C:\Temp。
The CHDIR command does not treat spaces as separators, so it is possible to change the directory name to one
Subdirectt names with spaces but no quotation marks. For example:
cd \winnt\profiles\username\programs\start menu
Same as the following:
cd "\winnt\profiles\username\programs\start menu"
In the event that the extended functionality is disabled, you must type the above commands.
Create a directory.

MD [drive:]path
If the command extension is enabled, MKDIR changes as follows:
If required, MKDIR creates an intermediate directory in the path. For example: Let's say no
Exists, then:
mkdir \a\b\c\d

tips.
