how manage the database

hi everyone,

i’ve just upgraded from kodi 14 to kodi 16
as i didn’t want to loose my databases, i used to diferents ways to keep it
– export in separate files from kodi 14
– use backup add on

i didn’t succeed in importing the kodi14’s export in kodi 16!!!
so i used the addon backup to restore database.
this plus a full scan with scraper seems to work fine Blush

the only question remain is that i have :
– a “Myvideo99.db” file in the repertory appdata/roaming/kodi/userdata/database
– a lot of .jpeg, .nfo and. actors (for actor’s pictures, fanart, poster…) in the sources repertories on my nas

it’s quite a mess now with these files on my Synology. Confused
i’m wondering if these files come from the export?!
i don’t need them anymore cause upgrade is finished ?

quite an obvious question for most of you, but thanks for your help
