Ok, if I understand correctly it's the modification of the list of aliases.... In short, type as under autocad on the command line? So here is the answer: "Tools / Options / File Location / Interface / Alias File Location"
Then go to the files and edit.
To activate it: type on the command line: "UPDATEALIAS"
