Could you please clarify your question? Is your large file not binary? I mean, which kind of transformation are you going to perform on file content before saving it again?

It's already a binary file! Try explaining exactly what you want to do. Alternatively just read/write the file in manageable chunks and do your transformation on each block.

You can use multithreading here. Reading the whole file is not recommended as it will be very slow, hence create buffers for each thread to store sections of the file. The threads will read from the assigned buffers and do the necessary operation.
Here is one brief answer which makes sense: http://stackoverflow.com/questions/3197187/multithreaded-file-writing[^].

Hope it helped.
