Connecting to the VPN network
Security is priority
After you received the zip file containing several .ovpn files, you should unpack it to a directory that only you have access to and not upload them anywhere. They contain the connection parameters required to gain access to the management network as well and thus need to be protected from outsiders. Treat it like a password.
