But remember: the file only exists if you (or a mod) created it using an external editor. If the file is missing, fear not—fire up the PES 2021 Player Editor, open your EDIT00000000 , export the players, and you will have a fresh Player.bin ready for tweaking.
In a fresh installation of PES 2021, Player.bin is not directly accessible as a standalone file. It is packed inside the game's .cpk (CRI Packed File) archives. These are essentially compressed folders that contain the game's assets. You can locate it in: Player.bin Pes 2021 Location
