let win32.hlp be with you:)
just make a view of not entire file but definite size chunk...

Yeah, i know ,i was hoping there's another way.

MMF is a great mechanism. but it has its advantages while file stays in RAM. if this chunk size is more than available free mem all advantages disparear - file goes to swapfile. i'd suggest you to check free memory status and then choose the MMF chunk size.(e.g 2/3 of free RAM)

Take a look at the example that I posted here:

It is written in HLA but should be clear enough for you to translate for other assemblers.
