[RESOLVED]How it's possible to remove source for addons ? I have a SMB source and i can't delete it.. help

This is the main problems… on my LAN 192.168.1.210 it’s no more present:
I don’t remember how i can add this source here… but now i choose:
Home -> Preferences -> Add-ons -> Install from zip

Now it’s present the default value:

  • Browser zero conf
  • Home
  • etc etc

At end of this list i don’t know how i have add this and i have:

  • smb://192.168.1.210

If i press enter on it… i obtain error on host… at this point from main list i have tryed to deleted it but i can’t…

EDIT
On OSMC i have installed and now it’s running the FTP Server… now i can access to my Rasp from my PC using filezilla:
If you can suggest to me what’s the exact file it’s stored this configuration i thinks i can try to edit manually from pc…
