Transferring junk on PS2 via USB

I have this little USB card thing that has like 256mb data, is there any way to get stuff off my ps2 like game saves and stuff and put them onto the card via the usb port on the ps2. I don’t want to buy anything, I’m just wondering if there’s some funky program to do that or anything, because I’m bored and am trying to make everything I own do things they aren’t suppose to, so far I haven’t even been able to make my dog make toast. :frowning:
