Name Mangler 2.0 - MacUpdate

Name Mangler... If you need to rename several files at once, this is the application you have always been looking for. Name Mangler is a batch file renamer that supports the following 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.

But 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.

New function for File List's Advanced Renaming: [truncate] returns a constant with (source expression) truncated to (maximum length) characters if (source expression) is longer than (maximum length). Returns the orginal (source expression) otherwise.
New function for File List's Advanced Renaming: [pad] returns a constant formed from (source expression) by either removing characters from the end, or by appending as many occurrences of (padding expression) as necessary.
File List no longer allows making files invisible by specifying a name that starts with a "." character. (Please contact me if you absolutely need this "feature".)
Reworded some preferences for better understanding.
Updated File List's documentation with a short paragraph on using back references in regular expressions.
