Cards with extension *.obf

Hello forum,
Download several cards but on the internal ram Sony Xperia phone. Is it possible to move cards to extended ram without the lost of connection to OSM program?

You have not mentioned the app you are using!!

But map files with *.obf belong to Osmand, I think.

You can move Osmand app to SD card itself via Android app settings,

and inside Osmand app you can go to its settings, and define the path where to store map files and other stuff. Change that path to SD card.
