This is going to re-allocate memory all the time, and I like to pre-allocate the needed memory for best performance. I remember having read an article about this many years ago (from Christopher) but I really do not remember anything about it, so I would be very thankful if somebody would give me a tip.

I could but I would expect this to take even more time, because as the file grows it would have to move it around quite a lot?
