I am aware of Exiftool, which does have a Windows GUI, but it is not clear whether batch editing of EXIF data is possible within this tool. There are many similar free tools out there which I found while searching. My goal in asking was to avoid installing ten programs to find the one that permitted batch EXIF editing.
I understand that folks have favorite alternative software packages they use for other purposes, but it would be helpful to have suggested software which the user knows will solve the problem at hand.
Has anyone used Exiftool or a similar program for the intended purpose?
