Ubuntu 15.04 Linux Does Not Support the "exFat" Filesystem?

[Teo En Ming]

Dear Ubuntu Users,

I have booted up my home desktop computer with Ubuntu 15.04 amd64 Live
DVD. Using a USB 3.0 card reader, I plugged in my 64 GB SDXC Class 10
memory card with the exFat filesystem. Ubuntu 15.04 pops up a dialog
telling me that it cannot mount the exFat filesystem.

I have also tried booting up my home desktop computer with Fedora 22
Workstation Live DVD. It too, tells me that it cannot mount the exFat
filesystem.

Is it true that, generally, the latest Linux distributions so far
cannot support 64 GB SDXC Class 10 memory cards with the exFat
filesystem? When will Linux distributions be able to support the exFat
filesystem?

My current computer hardware specifications are:

Intel 5th Generation Core i7 5820K @ 3.3 GHz with 6 Cores and 12
Threads Processor (Haswell-E)
MSI X99A SLI Krait Edition Motherboard with Socket 2011 v3 (Supports
USB 3.0 and USB 3.1)
8 GB Kingston DDR4 2133 MHz CL15 Single Channel Memory

I am looking forward to your advise.

Thank you very much.

Yours sincerely,
