Name Mangler 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's Droplets make it ridiculously easy to store configurations and use those repeatedly for different, alternating purposes. Just drop your files on them.
