I’m Chanpory, and this is my site on how to live and work better as a designer.

You should follow me on Twitter here.

Ever had to rename a bunch of files one by one? It’s tedious, time-draining, and soul-sucking. Next time, use Renamer4Mac.

This powerful utility lets you rename any number of files or folders at once. Features include all sorts of naming voodoo: search & replace, insert & overwrite, enumeration, and capitalization. Advanced geeks can rejoice, because it also supports regular expressions. All this and an elegant live filename preview of make this freeware app a necessity in every designer’s arsenal.

Windows users, I haven’t forgotten you. Check out Rename-It!

    Good topic. Also, Linux users may want to know about apps like Krename or pyRenamer.

    I’m a bit hardcore/old school when it comes to these kinds of things.

    I still prefer to write a quick script in php which I can run locally to batch rename, and with the likes of the GD library I can also deal with image resizing etc.

    Another one for windows users, that I have been using and found to be excellent and very powerful is PFrank: http://www3.telus.net/pfrank/

    In such cases I simply use Automator, which is shipped with Mac OS X Tiger :) Simply drag “Rename Finder Items” to your workspace, and you’re ready to go. If you’ll google, you’ll find Automator extension, that adds regular expression support.

    This is exactly what I was looking for last week, and the ability to live preview is without a doubt the piece that takes this way beyond automator and home-brewed scripts.

    Will have to check this out. For better or for worse I like to edit music file names and id3 tags by hand. Having to edit file names of entire albums to my own personal preference can be very tedious though.

    When I first came across this I thought it was nice to know about, but never thought I would use it. Turns out I have thousands of files to rename this week. Thanks for saving me several hours of frustration.
