I will try making a minimal working example on one “big” file (4500 KB) and share my readbytes! code with you and explaining setup.

I have been looking at Mmap but not been able to understand how to utilize it, so hope we could look at that too.

The example will hopefully come later today if you want to take a look at it, thank you.

Kind regards
