[JSP] organize the files when serving a game to download

Hi folks,

I have to develop a module of java games download.
I think it shouldn t be difficult, but I ve a problem when I try to see how am I going to organize my files and my information.

As for me, I already have a UserAgent database with id's.
I tought about creating a table mast_games, where there would be :
-idGame, gameName, UASupported,

where UASupported tiene el formato id1;id2;etc...

But my problem is to organize the physical file since I got games which are compatible with a group of cells ( ex : Motorola V3xx V4xx V5xx V6xx V80_Ver1-0, ...)
And I don t think we can say that there is a limited number of effective groups...
So I m a little bit confused.
Thx in advance
