I wish something is weird
I am on a windows 10
when i perform a IP scan i see the recalbox.
It does not show in my network in the file explorer.

ha ha
Resolved !!!
well i did push the ip in a File Explorer and i finally got access to the share folder.

From what i understand the process that is described in
"Extracting Rom Files" does not work as i am on V4.
How can i extact my Roms.
Thanks
