How big is it? Can you tell us anything else about it? (E. g., can
you see any text strings in it if you try to open it in Notepad or
similar [or try IrfanView which is pretty good at recognising image
formats])?
How did you come to discover its presence?
I am now guessing it was from a typo/accidental key press of some sort
while a batch was running. Probably a ")" key as Paul suggested. It was
a "flash" in a cmd window that I happened to catch so I went exploring
for it and the ")" at the end looked strange to me.

The file is empty and now renamed xxxNUL).

By empty, do you mean 0 size? If so, I'd delete it. (If it _isn't_ 0
size, it's not empty.)
