On Sony ILCE-7M2, Since 29 May, images taken to SD card won't transfer on Play Memories, Can send to phone by Wifi but just can't see the file on the SD card whether by Windows Explorer, or by Sony Play Memeories. Its there and I know its name, but cant see it on Windows Explorer. Its in a folder 100MSDCF, and I have not changed the file name prefix DSC eg DSC99999.JPG

Me again. I right clicked on the memory card and clicked scan. Windows said nothing wrong with card and it didn't need scanned.  Scanned it anyway and then it said it was repaired.  Well all the photos that wouldn't show up are now visible and I got them using Sony Play Memories Home
