I open my card on the in-body card reader in a Macbook Pro. The Canon and Lightroom programs pop up "not a file!" and I turn off the pop-up boxes. I wasn't successful loading from within SPP, so I just open up the card on the usual hierarchical file structure program ("Finder" for mac, "Explorer" for PC). I look for "cardname" > "SIG101" > individual files. Copy your individual files into a folder on your hard drive, and as mentioned before, do not put 100 or more files into that folder. In your case , copy the 126 files into two folders, approximately 63 each, for fastest loading.
