Writing file more 4GB
Hi Alex,

using "open/create file" once and then iteratively "set file position, write binary file, get file position", keeping the file refnum from open/create in a shift register and closing it after the loop has executed.
You don't need the Get/SetFilePosition as long as you keep the file refnum alive!

vielen lieben Dank, das vereinfacht die Sache erheblich
more over, when I wanted to reproduce the solution with using set/get file position - I wasn't able to reproduce my solution in a demo, which does mildly concern me.
so I followed Gerd's advice - and it works like charm!
I have put together this demo to write and read binary files bigger than 4 gb for anyone else how might stumble upon this thread - tested in labview 2020 64 bit with a 5 gb dump on a Windows computer with 16 gb of RAM
