How large can a .bin file be, the program says the file is too large on Pkhex

It says this pokemon ranch file is too big for PKhex

data.bin

That is not a ranch save file. Use homebrew to extract your save data, don't just copypaste files from SD cards.

The expected size is 0x54000 or 0x7C000 (507904d); your file is almost 6 times too large.

Ok, but the savegame manager Gx wont let me put in the save file
