Can you explain where are the files located?I don't play FM22. I only play fifa mobile 14 modded in my phone.
If you require the files, please play the game in a 'rooted' emulator like nox player, and once you claim your favourite players and play some matches, check the cache folder ( data/cache/) inside the FM22 data.
The file names will be random. You can open them in hex to see actual file info.. most of them will be png files, rx3 ( model and textures) , and some other formats like pvr texture etc..
