transform absolute path into relative xrif

[caspergt]

Good evening to all,
I have a mountain of files, and all xrefs are connected in the same folders, saiccome are under servers I would like to give everyone a "relative" path without having to open all files and reload the path... Is there a lisp or an external tool that does this?
