In the "Export/Import" Menu there is the item "Extract preview image from selected" and then "CR2/DNG files".
If I use this the software says:
0 output files created
No file with specified extension
<-END-
This is correct, but how can I say, that the extention is "CR3"?
It's important to point out that, as per the Sticky Thread (https://exiftool.org/forum/index.php?topic=4553.0) in this sub-forum, the exiftool GUI is no longer supported by it's author.
I can point you to the example command (https://exiftool.org/exiftool_pod.html#exiftool--a--b--W-d-f_-t--c.-s--preview:all-dir) that will extract all preview images when used on the command line. To limit that command to just CR3 files, you would just add -ext cr3.
Thank you, I gave it a try:
exiftool -b -JpgFromRaw -w _CR3.JPG -ext CR3 -r .
But I thought it would have been easier via the gui and an command within.
or use jexiftoolgui (https://github.com/hvdwolf/jExifToolGUI/releases) and from the menu "Other -> Export all previews/thumbs from selected"
Hello
... or use Metadata++ (Windows only), right-click the file and select Export Thumbnail
