categorizing raw folder in android?

I开发者_运维知识库 have around 300 .mp3 files. so i need to place it in raw folder. Is there any way to keep these files in a group (like animalvoice, birdsvoice etc) ?

I try to add a folder inside the raw folder to group 100 sound files in each folder. But resource id is not generating..

Any solution?

this is simply not possible.

if you you want to folder structure Assets is the way to go, but then you have to do your own path management.
