@thenouk If I understand correctly you want to use your flash drive as a personal storage device for various things, and as a storage device for Recalbox ROMs, is that it?
It is not recommended, although theoretically it is possible. There is a small risk of corrupting all files, and you should ideally avoid this risk.
If you want to ignore this, it should theoretically work for what you want, though it's not recommended.
