If you need to rename several files at once every now and then, this is the application you have always been looking for. Name Mangler (previously known as File List) is a batch file renamer that supports all common renaming tasks: Find and Replace (including support for regular expressions); Number Sequentially; Change Case; Set Extension; Add Prefix/Suffix; Remove/Insert Characters.

Moreover, you can combine all of these using the Advanced renaming mode, which even comes with some extra features, such as conditional statements, nested counters, and more.

Name Mangler is more than just one versatile renaming utility — it's an infinite number of task-specific renaming utilities: Name Mangler's Droplets make it ridiculously easy to store configurations and use those repeatedly for different, alternating purposes. Just drop your files on them.
