Renaming files is a royal pain in the proverbial (or, literal) patootie. Oh, sure, it’s easy enough to rename a single file, or even half a dozen files. Select the file in the Finder, press the Enter key, type in a new name, and, well, done.
Repeat that process beyond half a dozen to, say, a hundred files, and the tedium level rises in proportion to the potential for carpal tunnel syndrome. If you need to change the name of a few thousand files, even something simple like adding a prefix or suffix or extension or number, you’ll lose your mind before you’re done.
Enter vRenamer, the mass file renamer app for the Mac (and Windows PCs and Linux PCs). Just drag and drop a gazillion files on vRenamer, set the parameters to change the name, add a numbering scheme, change prefix or suffix or extension, check the Preview to make sure all is good, and you’re done.
What you can do to files is remarkable and actually goes beyond renaming, though that’s the bread and butter (can there be a ‘bread and butter’ element in a free app?). vRenamer renames files or folders, but it also renames music files using ID3 tags, and renames photos using specific metadata).
You can preview each renaming process before renaming. There’s a built-in preview for images (JPG, PNG and GIF), and files can be sorted before renaming). It even supports regular expressions.
What’s not to like?
It’s written in Java and you’ll need Java installed on your Mac (or Windows or Linux PC) for vRenamer to run. Java, as you’ve probably heard, isn’t exactly the most secure platform on planet earth.
If security is an issue and money is not, there’s always the Renamer app for the Mac; one of the best. But if money is an object, there’s the free Rename app, also one of the best, though it’s not as feature laden as vRenamer or Renamer.
