UNC addresses do not work

  An UNC address of a file, like 
 \\servername\folder\index.html 
 does not work. This is a legal file path and Firefox rewrites it thus:
 file://///servername/folder/index.html
 Amaya also rewrites the address in a way that never reaches the seeked file, something like:
 C:\servername\folder\index.html 
 Also, entering the file rewritten by Firefox does not brings the data but a "Not Found" error.
  
 All operating systems can read UNC files, including Windows.
