Do you mean you're storing data in ruby arrays and hashes? You might 
want to take a look at YAML[1]. Are the file names static, and is there 
a fixed amount of files?

Well, I'm sure it's not too hard, but I don't understand why you want 
to. Are you using that information for something, or do you just want to 
browse the directories?

Remember, IRB isn't a terminal.
