File Types for T5

[TheOrganGrinder]

I am sure this will not be a "New" topic. As I am a dummy with such things, has there been a publication anywhere telling peopie like me, who don't know a ppf from a pdq, which files are Styles (Rhythms), which are Voices etc. and wher do they play from, do certain ones have to "installed" or can they be played direct from a usb stick. When I bought my T5 (privately) a few months ago after playing the Organ for over forty years I didn't realize I would have to find an evening course in computer technology also.
Frustrated.
