e.g. other players will list files like this
file_1.mp3
file_10.mp3
file_2.mp3
file_3.mp3
file_4.mp3
file_5.mp3
file_6.mp3
file_7.mp3
file_8.mp3
file_9.mp3
file_11.mp3

EduPlayer will show them in the right order. No need to prefix files with zeros anymore.

file_1.mp3
file_2.mp3
file_3.mp3
file_4.mp3
file_5.mp3
file_6.mp3
file_7.mp3
file_8.mp3
file_9.mp3
file_10.mp3
