Strange Binary File Write Behaviour

[Strokes]

Something a bit strange going on when I attempt to write data to a binary file. I've replicated the issue in StrangeBinaryFileBehaviour.vi which is attached below...

I'm merely writing two bytes to a binary file yet my hex editor/viewer is telling me I have 6 bytes of data, a screenie of the hex editor dump of the binary file is also attached

Maybe I'm losing the plot and am missing something, forgive it's late on a friday

Wire a FALSE to the "prepend array or string size ...?" terminal. The default is TRUE so you get additional bytes, depending on what you wire.

For a 1D array, you would get 4 additional bytes for the array size (I32) and tha's what you are seeing.

I can't tell you how many times that has bit me in the arse.  I understand why the default it TRUE, but I have yet to run into a case where I actually wanted it to be TRUE.
