Hi, upgrading my phone, wanted to increase the size of my memory card. Put all the jpegs from the old card on a USB stick, fine so far. Moved the jpegs from the USB stick to the new memory card but when I tried to open them the PC said that it couldn't as the PC didn't recognise the file type or it was corrupted. Checked the properties on the transfered file and the un transfered file and they were identical. No idea what is going on. Also the transfer rate was very slow. Any ideas out there?
