Extract thumbnails for all images in a folder to another folder

[AndyBell]

Hi

I'm brand new to ExifTool.

I want to use it to extract the small thumbnail images from a folder and save them in a new folder.

So far I have

exiftool -b -ThumbnailImage -w .JPG -ext * .

and this works. But I want to save the thumbnail JPEGS to a different folder and I can't find a way to do that. The folder to save to exists, although I'd like ExifTool to create it it needs be.

If I can get that to work, then I'd like to get -r working, so that ExIfTool recurses all subdirectories and saves the thumbnails to a corresponding folder...

Thus - image folders:

c:\images\one
               \two
                \three

Thumbnails go in:

c:\thumbs\one
                \two
                \three

Is this possible?

Finally, is there a way to say 'all supported image formats' rather than *

Many thanks,

Andy

Hi Andy,

Try this:

1. cd c:\images

2. exiftool -b -thumbnailimage -w c:/thumbs/%d%f.JPG -ext * -r .

By default, exiftool will attempt to process all formats that it can write to.  I believe this pretty much covers most, if not all, image formats. And any image format that it doesn't cover is most likely not going to include ThumbnailImage.  You can probably just drop it.

This command isn't writing to the files, so it will read all supported formats without the -ext option.
