why it’s trying to open archives?

hi there,
i’m using kodi 16 on an android tv box.
i am playing stuff from a samba dir with a lot of stuff in it, not only videos. every time i try to play a video i notice in the log that kodi is opening all zip and rar archives, probably looking for subtitles or other contents.
i can’t find a way to prevent this, even if i modified advancedsettings.xml adding this:

Code:
<videoextensions>
      <remove>.zip|.rar|.iso|.bin|.pdf|.txt|.log</remove>
    </videoextensions>

any idea? thanks a lot
