Renamer: Batch File Renaming Made Easy

Isn’t it annoying when you import photos from your camera and they are all labelled some variation of ‘P1163954.jpg’. With Renamer, you can quickly and easily batch rename all your photos to ‘Car1.jpg’, etc, or even change the file extension. Renamer doesn’t stop there, it has the power to batch rename any type of file. Through a series of Automator like actions, your files can be renamed in a matter of seconds!

Renamer is developed by the team over at creativebe – who have also brought you some other fantastic apps such as iArchiver. The application doesn’t contain any unnecessary ‘frills’ and is excellent at what it does.

Batch Renaming

Batch renaming of files in Renamer is easy, efficient and the interface looks nice too! You are given total control the modify the name to your liking. In the examples below, I have taken pictures straight off my camera and onto my computer. As you can see they are of a generic name. With renamer, in seconds, they were a bit more organised.

If these are now brought into iPhoto, Aperture, Lightroom, etc, they will have the filename you set them instead of the cameras generic setting.

The controls of Renamer are much like that of Automator. If you don’t know what I mean, open it up and have a play around! Essentially, you add a series of ‘actions’ in the sidebar.

Adding an Action

Each action builds off the last one, modifying the name until you get what you want. You have four options when adding in actions. You can modify the characters, numbers, case and even find/replace items.

The main interface window is simple and intuitive. In the left pane are the files that you are renaming (files can be added and removed by clicking the + or – on the bottom left of this window) and on the right hand side is the sidebar with your actions.

Renamer has a great feature of giving you a preview of what your files will look like after you apply the actions, even before you apply them.

The actions I used in my example led from the photos being called ‘P1163954.jpg’ to ‘Photo1.jpg’. To do this I used three actions. First, I instructed Renamer to put the text ‘Photo’ in all of the files, at the front. The next action was to delete the remaining characters from the back (the P1163954). Finally, I wanted to add in a number for the photo, just as a separator to identify them.

Presets

If you run a batch rename often, you can create a preset to save you even more time. Simply click on the black bar on the top right and give your preset a name. From here, whenever you want to run this preset, just click on the black bar again and select it from the list.

For example: I made one called “Olympus Text –> Photo1”. This used the actions as described before.

Menu Bar

Renamer does have a menu bar that allows you to access the power of batch renaming straight from your Finder window. The menu bar icon gives you various options to convert your files names with some quick presets, or, you can even find the presets you have made in the list too!

Conclusion

Renamer is a simple utility application that serves one purpose, and serves it exceptionally well. For those who regularly work with lots of files – this application is a must have! Future improvements I would like to see, however, are more customisation in the naming (i.e. the ability to filter items), and the ability to batch colour label certain items. All in all, a great app!

What do you use for renaming files? Are you happy with the functionality built into Automator, or do you require something slightly more advanced?


Summary

A fantastic application that serves it's single purpose well. A must have for any Mac user that works with a lot of files. A great polished utility app.
