The Sony PlayStation 2 (PS2), like other sixth-generation home gaming systems, uses a proprietary memory card device to store gaming data. If you want to connect your PS2 to a PC for the purposes of transferring save files, you only need a simple adaptor.
You will need PS2-to-PS3 memory card adaptor to connect the PS2 memory card to your PC. Because the adaptor uses a USB cable to communicate with the PS3, this USB cable can also be used to communicate with a PC.
Insert your PS2 memory card into the memory card slot on your PS2-to-PS3 memory card adaptor. Then connect the USB end of the adaptor to an available USB port on your PC.
