Um. Context?

Plaintext file? Binary file? Whereabouts did it come from? Any observations, seeing as you have access to the whole file(s)?

If that seems like alot of work to you, here's your answer: 42.

If the file was created by an opensource app - just read up on it.
Otherwise, it's time for some reverse engineering

Ahhhhh, do u mean decompiling the program? im not sure how to do that

Its a reference to Hitch Hikers Guide to the Galaxy.

Actually it means figuring out how the encryption algorithm works so you can reverse it. A bit of a tedious process, but if the data is important enough, it may be worth it. If you know what program encrypted it or what algorithm, it could make reversing it much easier.
