C:\WINDOWS>HELP CD
Displays the name of or changes the current directory.

CHDIR [/D] [drive:][path]
CHDIR [..]
CD [/D] [drive:][path]
CD [..]

 ..   Specifies that you want to change to the parent directory.

Type CD drive: to display the current directory in the specified drive.
Type CD without parameters to display the current drive and directory.

Use the /D switch to change current drive in addition to changing current
directory for a drive.

If Command Extensions are enabled CHDIR changes as follows:

The current directory string is converted to use the same case as
the on disk names.  So CD C:\TEMP would actually set the current
directory to C:\Temp if that is the case on disk.

CHDIR command does not treat spaces as delimiters, so it is possible to
CD into a subdirectory name that contains a space without surrounding
the name with quotes.  For example:

   cd \winnt\profiles\username\programs\start menu

is the same as:

   cd "\winnt\profiles\username\programs\start menu"

which is what you would have to type if extensions were disabled.



C:\WINDOWS>HELP CHCP
Displays or sets the active code page number.

CHCP [nnn]

 nnn   Specifies a code page number.

Type CHCP without a parameter to display the active code page number.
