You can interrogate "files" as to what it is, and / or what methods it accepts:
files.class
files.methods.sort

Then you can check Ruby's documentation (or remember off the top of
your head ;) ) what other method would be appropriate (if any).

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.
