I bet the Apple user is a bit new at this. If the files do not show its possible they can't or don't know how to add NTFS support to their machine.
Try another Apple owner.
I'm a photographer and I'm trying to get raw images (.CR2) from my PC to another person's Mac. I think I have tried jpgs and they didn't work either so the file extension should be irrelevant but there you go just in case. It's a couple of weddings so they are huge files. Here's what I've tried:
*I put each folder on my external hard drive, 14G worth. When I am done I see that the images transferred fine and my hard drive is 14G fuller now. I hand that over to the Mac person and he says the folders are empty when trying to view from his computer.
*Then I got his external hard drive and ended up with the exact same result. His drive was 14G fuller and everything.
* I have burned discs for him and they come up empty as well
What do I need to do? Please help!
