Can anyone help me with the easiest, or most efficient way to browse through files and folders?
Background: I'm trying to create a media player application, that browses through folders and when i click on a file, it must do whatever it has to with it. So i got the file browsing part down, kind of...
This is what I have, it works, but when I open a file(.txt), close it, click on "back", and enter the same directory, then i have to click on the txt file twice just to open it again...
Also please criticise this code...im here to learn.
