FC doesn't do that, but if your using vb or Excel VBA, you can use low level
file io to open each and compare at byte level.

Working with Binary Access Files

It would be a lot easier to automate the check than to use hex editors.

I know the files aren't the same, but I want to make sure at byte xyz they
both have the same data type.

Right now I have both files open and I have to jump between them to check
that at byte 872 both have the phone number starting in that position.

I don't know about that, but have you tried the old FC command
(filecompare)
from the command window (DOS).

In the command window do

fc /? <cr

for information on options.

I didn't know what group to post this in... I'm looking for a good hex
editor. One that would permit me to view two files at the same time and
as
I
move the position in one it would also move it in the other. I'm trying
to
compare the position location of two files.
