This script exports the captions from all .jpg files found the directory it is in and all it's subdirectories (recursive) in a text file per directory.
How to use it:
- Install exiftool, as described here: Exiftool
- Download the file ExportCaptionsPerDirectory.bat_txt from the attachements below in this page, and put it in the directory from where you want the tool to start putting the metadata files per directory.
- Rename the file so the extension is only .bat instead of .bat_txt (uploading .bat files isn't allowed on sites.google.com)
- Doubleclick the .bat file
If necessary, you can change parts of the .bat file as you wish of course...
