Thanks for answer.
Yes, as you can see in image attached
on the left I see all libraries but on the right it jump from Battery_Holders to Connectors....
I checked in /usr/share/kicad/modules/Capacitors_THT.pretty/ folder and here I see 357 files.
Then it seems that all libraries have been copied in "module" folder including file contained, but not all of them are "usable".
Are filters the three icons on the right? If I connect my pc to internet then all footprints are available then I think filters are correctly set.
