Example: Importing Superfrog_v1.2_0035.zip does not work properly, game is not matched by LB and LB can't find any medata for it. But there is entry for it in files.xml, as 'Superfrog_v1.2_0035' , with proper name and platform.

  <File>
    <Platform>Commodore Amiga</Platform>
    <FileName>Superfrog_v1.2_0035</FileName>
    <GameName>Superfrog</GameName>
  </File>
