I bought an adapter where I insert de 64 GB micro SD card from my Galaxy S4, and wich connects to an USB slot on the computer (running Windows XP). The card gets a drive letter on Windows, but it says that the file system is not recognized.
I formatted the card on the telephone. I hope I do not have to reformat it on Windows since it will be a lot of work to re´nstall thousands of files on the card. And still the question is whether a Windows-formatted card can be handled by the software on the telephone.
