You might be able to download a free Hex Editor from the internet to help
read the binary coded part of the .doc file as long as you didn't resave as
a text file, which probably would have stripped it of it's formatting and
macros.
Also a recurring tip on these forums is not to open a Word document from any
kind of removable media for editing, because of the way Word constantly
interacts with its open files. It is better to copy it to a hard drive and
open from and save it to the hard drive, then copy the closed file back to
the removable media.
