The \ is an escape character, so you are actually checking for "c:
est_ruby" (\t is is the escape sequence for a tab character)

Either try

File.directory? "c:\\test_ruby"

or

File.directory? "c:/test_ruby"

Windows NT *at least* since Vista, but probably XP already, and maybe
even the original NT 3.51, support the forward slash in the command
line.

Though the folk I have met,
(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.
