Does it matter if I use sd card?

[dogeymon]

I have something that acts like a flash drive usb stick.

I have a 64gb sd card inserted in a usb sd card reader. I use that to put games in my pi.

They say I need format it for fat32 before using it. But since it’s a 64gb I can only format it for exFAT.

I have problems getting games onto the pi with this thing a bit. Should I be using an actual flash drive memory stick? Or does it matter?

@dogeymon As long as the OS can see it as a storage device, you can use anything that connects over USB.
As for the FAT part: if you just want to use it for transfer and not permanently attached to the PI, then you can just partition it in 2 smaller parts and just format the 1st partition as FAT32, making sure its size is less than 32 GB.

I haven't tested it, but apparently if you use the command
sudo apt-get install ntfs-3g
it'll install NTFS read/write support onto the Pi.

That said, I think this is already included in RetroPie, as my NTFS formatted 32GB USB drive is read fine by RetroPie.

I'd format the SD card to NTFS, add the RetroPie folder to it, plug it into the Pi, and see if the Pi populates the folder. If it doesn't try that command to install NTFS support.
