Wild Cards on the Line

Although many people use the Windows XP Command Prompt, I have found that very few people know you can use wild cards at the Command Prompt. Let's say you want to move to a directory with a long name. Let's assume as an example that you're in the root directory of drive C:, and you'd like to move to the Program Files directory (folder). Since wild cards will work, you can simply type
cd\prog*
press Enter, and there you are.
So what happens when more than one directory satisfies the match? Don't worry. Windows XP won't get confused and lock up. XP simply moves you to the first directory that matches the wild card specs.
