So for instance, I want to create a file called "message" that contains text only, how. How does the system know what program to use to read it if I decide to call it:

message.txt? message.dat? message.enc? message.cpz? message.asdfasdf? message.abcdefghijklmnopqrstuvwxyz? message.this_is_so_random? or just 'message' with no extension?

  • message.txt?
  • message.dat?
  • message.enc?
  • message.cpz?
  • message.asdfasdf?
  • message.abcdefghijklmnopqrstuvwxyz?
  • message.this_is_so_random?
  • or just 'message' with no extension?

Yeah, I was wondering this for text-only files, but also what about files that contain video and audio?
