I'm using Batocera on RP3. Trying to add bios over windows network (in the share/bios folder) it say's that cant copy because of lack of space.
But there's free space on the SD 🙁
Have you tried to reboot the device? Maybe a glitch causing this
KryPtAlIvIaN yep.... will try from another computer later and post the results here.
Could solve this using Filezilla in other to transfer the files.
