How To Associate App With A File Type

[Annette]

I am a guitar player and have downloaded some gp5 guitar tabs.

I have also downloaded tuxguitar which can play gp5 files.

When i try to open the files from myfiles i get cannot open file search googleplay.

When i open the files with total commander im given a list of apps and have to select tuxguitar every time.

How do i set tuxguitar to always always open gp5 files?

Why is everything so difficult in android?
