This texts to comments tool will read text files that have the same base name as an image and apply the text to the image's comments. The text files can be within the project, alongside the images, or in a separate location.
You can process the whole project, the displayed folder and its subfolders or only the displayed folder. The texts can be prepended, appended or applied to the comments field.
Run the tool, select the location of the text files, select the scope and text option and click OK. The number of edits made is displayed along with a detailed report in the system console.
