Atari ST files

[DragonsLover]

Using Steem, I was able to copy all the Atari files contained in Lemmings on my hard drive. Some of these files have no extensions. I was wondering, is there a way to convert or edit these ST files? As I can see, some of the files are the musics, some others are graphics and objects and some others are levels. Here's the list:
