Recently I used an external drive to move game files of fallout 4 to my pc from my Xbox One. After doing so the file is in an unknown format, and I cannot reach the archive of this file. If anyone knows how I would be able to access the archive, or a program that can help, that would be very helpful to know.
I've not seen any publicly released ways to explore files extracted from an Xbox One unfortunately. As a side question are you able to confirm this tool no longer works? Copy and Extract content from an Xbox One USB Formatted Drive on a Windows PC. I extracted content a few months ago, however no longer appear to be able to.
Actually that tool is how I got my files it does still work. First format your drive to Xbox One using the file converter. Then move your files. Connect to pc and swap it to pc mode. Disconnect and reconnect the drive. Then it should work
