I'm trying to make my own program that can help me manage my
files/folders faster than Windows command prompt but I have ran across a
problem.

The problem is if a user tries to open a folder while the program is in
"open text file" mode, it will close itself.

Code: http://pastebin.com/uFtpji0H


My question to you is, why is this File.readable not working against
folders? Is my code bad? Help me.
