Hi, I just had a quick question about file I/O in cocoa. In my previous applications I've managed to stick to the general NSData/Dictionary/etc writeToFile:atomically: methods, which work quite well. I'm currently writing an app that will be reading in lots of data over USB (up to multiple GB) in ~64k blocks and I want to write them out one after another. I've had a look at NSFileHandle but a quick test of using it didn't seem to write a file out. Is this where I should be looking or is there some other class that would be of more benefit?
