The idea arose from the stereo of my father's car is not there an iPod Shuffle. Then I thought
Since he does not randomize well, why not bring the names of the files already randomized?
I decided to take no time in Java and gave it there:

The form is simple to use, an example follows below:
RandomFiles.randomize ( "D: \ Test \", false); RandomFiles.randomize ( "D: \ Test \", true);
For the first call the output is:

Outgoing messages are used only to monitor the implementation of the program.
I hope it's useful to someone as it was for me. When you have time I will make a version of Python and / or Shell-Script and also install a decent OS (eg saw the garbage, right?) Here in the PC in the house of my parents.
