If I select refine RAW with one image and click on convert and try to select a folder, I get a message that the folder cannot be created.
Could you be more specific?
You select a raw image (thumb) and right click and select REFINE, or you slect the thumb and click CTRL + Enter and the refine screen come up.
Please advise where you try to select or create a folder, and where is convert?
The only Convert I can think of would be a right mouse click menu with some images in the queue offering CONVERT which would convert the images in the queue to your output file type.
The 7D is included in the files that QSE will decode, so I assume you are seeing a proper thumbnail image.
