It has a bit of a learning curve, which is a bit silly for something as simple as renaming files. It's an app which comes built into every Mac. Prior to the Yosemite (Mac OS 10.10) update, you had to use a tool like Automator to create a workflow and set a series of rules each time you wanted to rename files.Īutomator is still a very valid and powerful option. All the files will take on the new naming scheme. Once you've entered a new format and tweaked all the desired settings, click Rename. You can also choose how to number the files - either by index starting with a set number, a counter that starts at 00001 or with a date and time. You can search and replace certain words or numbers, add text to all the file names or completely reformat the names. A Rename window will appear with a number of drop-down fields to select from. To use the tool, select all the files you want to rename and right-click. With Yosemite came a powerful and very lightweight inbuilt tool in Finder for renaming a large selection of files. You don't need to buy or download an app to do it either.Įvery Mac comes preloaded with at least two options for batch renaming files. If you're working with a bunch of files on a Mac and you find yourself needing to uniquely name each and every one of them, you don't have to rename them one by one.
