Recuva (>=1.38) reliable on exFAT-formatted media?

Just because I cannot readily find the info under "Recuva Features":

Will Recuva work reliably when trying to recover accidentally deleted digital camera image files on an exFAT-formatted CompactFlash card? I.e., does it fully support exFAT?

I would be using Recuva v1.38.0.504 under Windows XP+SP3, KB955704 installed.

I?m asking this for a friend who is photographer and deleted some important images. Fortunately, he switched the camera off after recognizing his error, and immediately removed the card. We?re assuming exFAT, because the card is 64 GB and his card reader could read it only after installing the exFAT drivers on his system. (He lives about 500 miles away from me, so I can?t readily check myself. That?s why I?m asking before I recommend Recuva to him.)

Has anyone tried that successfully (under XP, preferably with a CF card or other medium > 32 GB)?

Thanks in advance!
