How to STOP Kodi downloading meta data

Hi All

I have been using XBMC and KODI for a number of years and have always processed my movies in Media Center Master which downloads Metadata to the movie folder on the NAS.

I’ve noticed that my HTPC is now full with more Metadata, how can I stop this happening?

I want KODI to refer to the Movie folder to pull Metadata and not locally, to save space. Is this possible?

Or should I NOT be downloading meta data via Media Center Master?

Thanks
Philip
