Windows 10 PowerRename is a free utility from Microsoft that allows you to bulk rename batches of files. It’s part of Windows PowerToys, a program containing multiple helpful utilities. To use PowerRename, you must first install PowerToys. (Click here to learn how to do that.)

Once you have PowerToys downloaded and installed, here’s how to use it. Select a batch of files you want to rename in File Explorer.

Right-click and choose PowerRename from the menu that pops out.

This window will open.

With PowerRename, you can:

  • Change the names of a large number of filesĀ (without renaming all of the files the same name).
  • Perform a search and replace on a targeted section of file names.
  • Perform a regular expression rename on multiple files.
  • Check expected rename results in a preview window before finalizing a bulk rename.
  • Undo a rename operation after it is completed.

Search for the files you want and choose how you want to rename them.

You exclude files, folder, or subfolders and choose options like making everything uppercase or lower case.

A preview window will show you what the renamed files will look like. If you’re satisfied, click on Rename.“
