Upload & Sell: Off
OK, so I re-tried: I put a formatted card in the camera, took one photo, then put the card in the reader and hooked it to the computer. Now there is a folder system on the card (a formatted card is completely empty), so I dragged a Raw file to the DCIM-folder, and then to the Number_Fuji folder (not the MISC-folder). Then put the card back in the camera, and I was able to see the Raw file, and process it. However, when I click on the arrow-buttons on the back of the camera, the LCD-display says "READ ERROR". Sounds not so healthy...
And the JPG I made has a number totally different than the Raw-file, and is imported to a new folder on my Mac...
