worker filemanager and some

[alvins]

hey..

was wondering if someone could help me out with worker filemanager. cant
seem to associate text files with gvim or mp3 files with mpg123. went to
the authors site and found some docs but cant really make anything out
of it. downloaded the manual but it looks like some of the pages are not
there? 

anyways, tried to associate some text files with 'own command' but
after that, all the other (unknown) files are 'text' files. so what am i
doing wrong? 

so, if anyone here is using worker, could you help me out? 

thanx
