Scan your harddisk with Java

It took me a few hours but i've managed to write an application that scans a harddisk to show directories, subdrectories and filesize etc. It took me so long to write this one because I had some trouble accessing subdirectories but i've sorted that one out. Everything is now dynamically done and should work fine.

I'll release if after some more testing and I'll will also a few other features such as writing the results to disk and maybe a GUI for easy navigation trough the application. After thats done i'll release the sourcecode here so you can play with it yourself.

Here's a demo I made that counts the frequency/occurences in a given string. Took me an hour or so to write it but it was fun to do so on a boring sunday. It also counts a few special character such as spaces and brackets etc.
