This is nothing new, I think it dated already from Recalbox times, and I was always putting it on the
back from the Filezilla guys. I was wrong. Because it happens just if you are connected to Batocera/Recalbox
as server from your local site. The filesize displayed is limited to 8 characters and leads to some funny stuff,
as it cuts the decimal position and for files in the giga size, at 10% of transfert it shows 100%. But after the rest is transfert correctly. So an information issue, but annoying as capacities on server site are always displayed wrong.
In the times of smaller games, I think that this error never appeared.
