I try to transfer rom files from pendrive to my SD card through KODI file manager, but I don’t have access to all folders and system files. Do I need root access? Is it possible without connecting RPi to router?
Which folder is not accessible?
Basically there are certain folders you can only write to as root (but ROMs should go into those) or hidden folders (which you can enable visibility under settings
Did you try Google?
Who is this Google you speak of ? Never heard of him before
