When you type:
cd /? at a CMD prompt, you receive:
CHDIR \[/D\] \[drive:\]\[path\]
CD \[/D\] \[drive:\]\[path\]
.. 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."
The /D switch is new, allowing you to switch Drives and folders in a single command.
A nice undocumented option is the wildcard (*). Type:
and it will switch to the "Documents and Settings" folder, the first folder to match the do<anything> pattern.
