A more detailed, step-to-step description on how to use the PPA pointed to by StalkerNOVA can be found on stackoverflow, copied here for the sake of completeness:
Do only once:
- Add the repository:
sudo add-apt-repository ppa:relan/exfat
- Update the package list:
sudo apt-get update
- Install the exfat package:
sudo apt-get install fuse-exfat
- Create the mount folder:
sudo mkdir /media/exfat
Everytime you want to access sdxc the card/exfat filesystem:
- Mount the filesystem (replace sdc1 with your exfat partition):
sudo mount -t exfat /dev/sdc1 /media/exfat
On some devices, cameras, for locked sdxc cards etc you might want to mount the filesystem read only, just add -o ro to the mount command line: sudo mount -t exfat -o ro /dev/sdc1 /media/exfat
- Read and write to /media/exfat to your heart's desire.
- When you are done, unmount the filesystem:
sudo umount /media/exfat
The sdc1 in the step-by-step above refers to the linux device where your card/exfat filesystem resides on. If this changes (usb card readers, cameras) or you simply don't know which one it could be either use the menu system System -> Administration -> Disk Util and usually you will find your camera or card reader in the list on the left hand side. Or - as a quick shortcut - use cat /proc/partitions on a terminal command line. The latter is only useful if you know all the other unchanging device names on your system and thus can quickly identify the one added one.
