Name Mangler is a blazingly-fast multi-file renaming tool that’s incredibly easy to use.

• Create single or multi-step renaming actions, save them, and share them across Macs
• Rename in excess of 2,000 files per second
• Use files’ metadata (e.g. ISO speed, dimensions, bit rate, etc.) in new names
• Before and after views of your filenames insure you rename them as you intend
• Save renaming tasks as droplets: just drag-and-drop files onto a droplet, and they’ll be renamed
• Load any previously-used rename action from the History browser

Name Mangler 3 represents a quantum leap forward in file renaming: speed and beauty combined with ease of use, and loaded with features.

For those coming from Name Mangler 2, here’s what’s new in this version:

— Tons of new features —

• Multi-step renaming lets you perform complex renaming tasks without touching Advanced mode
• Metadata accessible for use in all renaming operations, via an intuitive metadata browser
• Save any renaming action as a Preset, and automatically sync those presets across Macs
• Export renaming actions for sharing via email, etc.
• History keeps track of all performed actions, making it simple to reuse these actions
• Revert last-used renaming operation
• Shift-drag to file list will add the dragged files to the existing list
• Delete presets (and snippets, see below) from within Name Mangler by using the Option key
• Optionally display only files that will be renamed, instead of all files in the list
• Automatically detect potential duplicates and flag (or optionally automatically fix)
• Finder is no longer required to be running to use Name Mangler
• Check for file writable status and warn user if files are not writable

— User interface improvements —

• Fully retinaized for the retina Mac laptops
• The pop-up button for the rename operations has been moved out of the toolbar
• The ‘Rename’ button is in a more logical and visible spot
• Choose a dark or light appearance for the file list area
• The rename action area can be expanded horizontally
• Status lights next to each filename deliver at-a-glance info on renaming state
• Interim results show filenames at each step of a multi-step renaming task
• Tooltips show original names, new names, and errors
• Query field in Find and Replace makes it more obvious when in regular expression mode
• Status light for regular expressions shows syntax checking state (green=good, red=bad)
• New large icon view
• Automatic view mode determines what details to show based on sort order

— Mind-boggling speed improvements —

• Load tens of thousands of files from Finder in only seconds
• 50 to 100 times faster than Name Mangler 2
• Rename from 1,000 to in excess of 2,000 files per second
• So fast, you may think it’s not doing anything…but it is!

— New/improved renaming actions —

• New action: Compose, to start with a completely blank slate
• Split Insert/Remove into two distinct actions
• Split Prefix/Suffix into two distinct actions
• Sequence has been greatly simplified, thanks to multi-step
• New Sequence formats: Roman Numerals and Letters
• Sequence start and increments can be negative
• Increased the maximum and minimum limits for Sequence values
• Arbitrary Terms is now a format in the Sequence action
• Arbitrary Terms can take a CSV formatted file as input

— Advances in Advanced mode —

• New function: [random (number of character) from (pool)]
• Auto-complete functions and variables
• Tab to next empty parameter
• Auto-indent
• Selection (or line) can be shifted in or out via Command-[ and Command-]
• Find and replace
• Save any Advanced program as a Preset for easy reuse
• Create snippets of portions of code for easy reuse in other Advanced programs
• Automatically sync snippets to multiple Macs

What’s New in Name Mangler 3.6

New Features

• Added a “Group by” feature to the Sequence action. This can be used to create independent sequence numbers for files in different folders, for example.
• Single-file sequences can optionally not have any sequence number. (Focus on the “Group by” input field, then choose “Insert Laziness Indicator” from the “Edit” menu.)
• Title Case conversions can now either keep existing formatting for words shorter than a certain length, or convert them to lowercase.

Bug Fixes and Improvements

• Resolved an issue that made the Rename button invisible when using Dark Mode and Increased Contrast settings. (Hat tip to William H. for finding this one.)
• The file list can no longer be cleared during a renaming operation.
