Not sure how exactly you'd do that... I'm not possitive on how well RAM acts as a storage device... its "random access" after all...
Since I'm on a morrowind kick... its like little boxes to put stuff in so you dont have to carry all your lewt, so you can get more lewt... or something...
There is probably a way to do it, but not unless you put the data in an open file or something then save it like that...
Come to think of it, I'm not sure using RAM to temp store would even make sense... it'd still have to write eventually....
