Where is the imported oven file in iPad?

[athena]

Hello,

I am going to reset my iPad to factory setting due to some problems. But I want to use the same ovpn files I used earlier. Where are they? I had loaded them to iPad by using iTunes ( by dropping these files into the openVPN in files. How can I export them to A PC so that reload them into openVPN after restoring the OS? I can use iTunes in my PC again to import them

Thank you?
