Oh, helpful tip: (I wonder why I never new that before)

In the Windows Command Prompt, you can use the TAB key,
to fill filenames.

for example, if you have the directory

c:\mystuff\mommy\pic_10_2_1980_drunkInCollege\
and you are in

c:\mystuff\mommy\

just enter cd p (then press TAB) , to fill in the filename that
starts with p.
(sves you some typing when using the Commandpromt alot)
