For a digital art project, I'm looking for some kind of program that will open files in a random order. I have 20 files of different types, a few docs, an mp3, a few htms and I'm looking for a way that the user could have a folder of these files and then start a program that will open a random file and wait for user the user. When the user clicks or presses enter or any other trivial reaction, the first file will close and another will open. I'd like this to continue until all the files have been seen, no repeats and then its over. Is there something out there that will do this? I tried coding something but I only know very basic java and I'm rusty at that. Any ideas?
