How can I make the game/application get a random file from a directory? Like if the 'random' button is pressed, it gets just some random file from the directory and then says or something. Can you help?

I don't think it's possible... but why would you want to?

It is possible. The way I would do it is create a list box (it can be "invisible at start of frame" if you like).
In the event editor (or behaviour editor) have it load the file list from the specified directory at the start of the frame.
Now, select a random number that is from 0 to the number of lines in the list box.
Read the line based on the random number and bob's your uncle.

Andy: 
Something very important I forgot to mention is that if you have selected the checkbox in the listbox properties that says "1-Base Index" then you will need to read the line from the listbox based on Random + 1. This is because instead of being from 0 to Total - 1, a 1-base index uses numbering from 1 to Total.
If you dont have it selected, use the code I said (which is from 0 to Total - 1).
Your game wont crash if you have it either way, it simply wont load a file if it happens to choose the 1 number that is outside the boundary.
Mike
Just to reiterate so I make sense:
0-Base Index
"open " + appDrive$ + appDir$ + GetLine(Random(NBLines("Listbox"))) " alias music"
1-Base Index
"open " + appDrive$ + appDir$ + GetLine(Random(NBLines("Listbox")) + 1) + " alias music"
Please note that the above lines are not exact code as you would enter them, you will need to check the NBLines and GetLine functions using the Retrieve Global Value button in the Expression Editor. Plus the command itself will change depending on what object your using to play the music file. In this example I've demonstrated with the MCI object.

Thanks!
Weston L: Yhis is for a level selection. If you press the random button it vhooses a random level.
