Great app that helps me deal with the river of media files submitted at our community media center. This app lets you blast through reams of files, to standardize naming schemes, and clarify contents so that humans looking at them know what they are dealing with. This is just one of its many potential uses and well worth the money. This makes changing naming schemes so easy (and its visually dynamic so you can see potential changes before applying them), you’ll never dread re-organizing your file libraries or acommodating requests from others to do so. Basically this makes file renaming so efficient that lots of doors will open to what you can do (because hand renaming thousands of files is not reasonable even if it is possible). I have used this app since version 2(?) and it just gets better and better, which is why I am writing this review :)
BTW, if you understand Regular Expressions or are willing to learn them (RegExes are useful to learn if you are a programmer who needs to do lots of text processing), you can create even more sophisticated matching and replacement patterns. However it is not necessary to learn RegExes to exploit this app.
