If I understand what you are asking here, yes. If the size of the file 
is too large to read the entire contents into memory, sure you can open 
it using binary or random access mode to compare records and write them 
back in a sorted order. It will be much slower than if the work was done 
entirely in memory, but yes it can be done.
