Hi! As stated earlier, I am running Windows 7 on a Mac. Whenever I insert my S. D. card in the card slot or connect a card reader with a flash card and push f4, I get the message that the software is unable to locate a folder in which to download the information. When I open the tree view, Ionly find a floppy disk A., and the DVD. player D. in the group of removable storage devices. Now, on the mac side the reader or S. D. card show up fine. When I go into Windows explorer same thing. Quite frankly I have no idea where to go to make the card reader or S. D. card visible and I am just starting here to see if any of tec support has worked on a mac with this situation. Likely, I am missing something very simple here but I don't know what I am supposed to be looking for. Any help would be greatly appreciated. Thanks in advance.
