windows - What are ". " and ". . " in a directory? - Super User
The . is the current directory. You rarely need to use this; most commands will assume the current directory. The . . is the next level up; this is a rather useful shortcut. If you are in C:\foo\bar and you want to go to C:\foo\bar2 you can say. cd . . \bar2 and you will be in C:\foo\bar2.
