I use the intermediary of a serial file in the 'raw' folder - read it in java or c. I read this file line by line. Its kinda using a file instead of RAM to store loads of strings. Works for large files AFAIK and reads are fast. Also I do not have the problem of garbage collection or emergency memory clear outs that can happen (sh-t happens)
