When you need it, it’s wonderful

This app can be a lifesaver. If you need to edit file properties on one or a bunch of files this app will do exactly that. The user interface does a few things in non apple standard way so I give it 4* not 5. Here is an example of my need. Somehow mac OS managed to change the creation date on several hundred files in a project and them equal to modification date. That made sorting files ugly for me. But the EXIF data and the GPS data were not corrupted. I could set the creation dates on all the files to be the EXIF Digitized Date (the REAL creation date) as a fast batch job. WHEW! What a lifesaver!

I found several other uses. If you still remember your Unix command lines, and love scripting, you can get by without this tool. Maybe. If you are a mere mortal this app might be a Godsend. You might have to actually read the manual and still play around a bit. The hover descriptions are pretty good even if the icons are not always obvious.

Hard to use, but helpful.

I’m a professional photographer and I messed up by setting both of my cameras to the same time in terms of numbers, but one was AM and the other was PM. This meant the entire day was out of order. Thankfully after some quick tinkering in this app it was as if the problem never happened. Only reason it’s 4 instead of 5 stars is that the UI is really difficult to use.

Even though I paid the $9.99 for media properties, this app doesn't even show them for the audio files I've selected, let alone offer the ability to edit them! This is a total rip off! How is this even allowed in the App Store???
