Use fsutil with emacs

[etienne]

Hi,

here is the story of my problem.
I want to have use latex and bibtex on emacs and have only ONE file
with extension .bib
Let call it biblio.bib
Now on my tex files that in other directories, I want to use this file
to make a nice bibliography.
If I write
\bibliography{biblio} it does not work because biblio.bib is not in the
same directory if I put all the path c:\directory\biblio...it does not
work.

So I have try to use an hard link like ln on unix.
For windows the command is fsutil hardlink create <new name> <oldname>
for example
fsutil hardlink create c:\bibliography\localbiblio.bib c:\biblio.bib
if you do that and one modify one file, the other is also modify but
not if it is modify by emacs...may be because emacs doesn't use really
the file but a copy...I don't know.

As anyone as an idea to have only one file with extension .bib or to
solve this fsutil command ?

thanks you very much for your help
