Gets it Done
While this software is not documented, it is fairly straightforward and seems to do exactly what it is advertised to do. You can either drag and drop images to the application for processing, or you can add them via folder. I tried it both ways, dragging a few files at first and checking output, and then adding an entire (large) folder full of images. I used a tricked out MacBook Pro with 8 GB of ram and an SSD to process a folder containing 44,000+ images. It took an hour, but it did what it was supposed to do.
It appends "-private" to the name of each image processed. There is an option to change that to something else in preferences, but you cant save it and it doesnt remember it. That was OK in my instance, because I then used "Name Mangler 3" to restore all of the original names in a separate folder. I would personally like to see the software enhanced to replace select Exif data, but this did what I needed done. Will use it again.
Note: Adding this next day. One curious thing about this software is that it INCREASES the size of images by 50% or more. I didnt notice it initially, but caught it when Time Machine wanted to back up the new folder. Of course, Im talking about 45,000 files, not just a couple, so most users may not notice the difference.
