Too lazy to type the full directory name?

Did you know that you can avoid typing full directory names when changing directories from the Command Prompt?
Let's say you have a directory named MyNewYorkOfficeFilesFolder that you want to changed to. Instead of typing:

CD MyNewYorkOfficeFilesFolder
next time try:

CD myn*
If you have multiple directories starting with the letters "myn" then you'd have to use more characters before the *, until the name can be distinguished from the rest of the directory names in the current directory.
If you have multiple directories to change to such as:

MyNewYorkOfficeFilesFolder\AGroup\Outbox
you can use:

CD myn*\a*\o*
