Does anyone know a Dos command that determines if a file has 0 kb size? thank you

Not a command, but a well known trick (under DOS only) is to try to copy the file; if the file has 0Kb size the copy fails and you can test for the existence of the target, if that does not exist the file's size is zero.
So e.g.
Copy Zero.ext Zero.tmp If not exist Zero.tmp Echo Zero has 0Kb size Del Zero.tmp
That can be embedded in a batch to achieve your target.

IVO,
That's slick. Does that work in 3.x - 7.x?

The trick works fine under all DOS-kernel based systems, i.e. Windows 3X/9X/ME and obviously the related DOS subsystems (DOS 7.X).
