If you need to do some serious file renaming – perhaps you have folders stuffed with horribly named photos – try a bulk file renaming utility. There’s one called Bulk Rename Utility that’s free to use. It looks pretty ferocious when you open it up, but don’t worry – although it has enormous power and flexibility, it makes very light work out of actions such as changing the case of a bunch of file extensions.

Here’s how you change the case of all files in a folder using Bulk Rename Utility:
- Open the folder containing the files.
- Right-click any file in the folder and choose Bulk Rename Here from the context menu. The utility will load all the files into its main window, with a folder tree displayed on the left allowing you to navigate to any other folder, and a mind-numbing array of options displayed below.
- Press Ctrl+A to select all the files in the folder.
- Down near the bottom right of the window you’ll see Extension. Select Lower from the Extension drop-down box. You’ll see the filenames updated in the New Name column. This is a preview to let you check whether the changes you’re making are correct.
- If you’re satisfied with the displayed changes, click the Rename button in the bottom right to rename the selected files.
A quick look at Bulk Rename’s other options gives you an idea of the power of the program. You can even save renaming schemes so that you can reapply them to other batches of files.
TIP: If you rename a bunch of files using Bulk Rename and the changes don’t immediately appear within explorer, press F5 to refresh the view of the window.
