I think it’s longevity in the Mac application world speaks to its outstanding usefulness. I’m new to this app and already can’t believe I’ve waited this long. If you have a long history of files like me (umm, dating to 1995), then this app is a savior! I’ve recent digitized thousands of negatives from the past, and together with an EXIF editor (MetaImage!) Better Rename 10 makes this job so much easier. Once properly tagged, BR10 can see the data and build custom file names so my image archive is organized exactly the way I need it. Oh, and it’s great at renaming all those “Screen Shot…” files that you want to keep! This is an incredibly useful app.
