Tip: Command prompt "start ." = Open New Explorer Window Here

Here's a quick tip on a command-line shortcut that I've found myself using a lot since discovering it.

At a command prompt, type:

start .

This opens a new Windows Explorer window at the current directory location of the command prompt.

(This is usually better than typing explorer at the command prompt, which also opens a new Explorer window, but at the default directory location instead of the current location.)
