Gaming Extract the .bin save files from .3ds roms?

[Polarise]

Hello, I would like to know if there is a way to extract the .bin save file from a .3ds rom or the .sav because when I browse the powersaves backup file, I see a .bin file that seems to be the save data backup. Is there a way to extract the .bin save file from a .3ds or .sav file using an application?
