bios folder change

I am trying that the bios folder is inside retroarch modifying an emulestation cfg but the folder does not recognize me, how can I do it.

/retrobat/bios to retrobat/emulators/retroarch/bios change

Hello.

Why is the reason to doing so ?

because I have many folders in the main folder and I would like to reduce them to find them more quickly but I do not know if it is possible

It's a nonsense. We don't care about the amount of folders... You just to take care about bios folder and roms folder. After that, you just have to click on retrobat.exe and it's done... Nothing to do inside the other folders.

Have you looked at your Windows folder how is it inside ?

But it is possible to do it or not, I just wanted to know

Maybe, maybe not.
As for as your will isn't clear...
