Hallo! First of all thanks a lot for very useful programs ExifTool and GUI. I am keep on photography and now I try to invent for myself a storage system for my photo archive - and since I have found these programs, this process promise to become easier and more comfortable. But I can't find how to do batch change of embedded preview in RAW files (canon CR2). I am not programmer, and of course it is easier to use GUI. And I don't find in ExifToolGUI this option. If you can help, I would make a .BAT file to automatize this process, or may be there are prepared solutions of this problem. The CR2 files and JPG files have the same name except the extension (CR2 and JPG accordingly). There is a lot of .CR2 files in a folder and I need to change embedded JPEG-previews inside all of them. JPEG files are in the same folder or in another one - it doesn't matter. Please help me with your advice. Thanks in advance.
