Easily Bulk Rename Files on Windows

In this tutorial, I will show you how to rename several files at once in Windows 10. You not only can append text to filenames, but you can even create advanced regular expressions or enumerate your files. There are also text transformations available to make your filenames all uppercase or lowercase.

To get started, I will be using PowerRename which is part of Microsoft PowerToys.

Installing and running Microsoft PowerToys


  • Windows 11 or Windows 10 version 2004 (code name 20H1 / build number 19041) or newer.
  • Our installer will install the following items

You can install PowerToys by heading to this link and downloading the executable for the latest release (as of writing this, it's called PowerToysSetup-0.31.2-x64.exe)

Once it's installed, you should be able to see PowerRename as an option in your Right-click menu when selecting files in your File Explorer.


Once you click that, you should see a popup come up with a search box, replace box, some options, and a preview.


To make a simple word replacement, you can type the word to search for in the first box, the word to replace it with in the second box, preview the results, and click "Rename".

If you want more complex replacements, such as matching several different words or characters, reordering parts of the filename, or duplicating sections, you can do that with Regular Expressions.

For example, to match the words "Lab" or "Lecture" in a filename, we can use (Lab|Lecture) in our search text. Just make sure to click the box for "Use Regular Expressions."

To rearrange parts of a filename, you can reference capturing groups in the replace text.

For example, if you had files that all ended with a 2-digit number and you wanted to move it to the beginning, your search text may be in the form (.*)(\d\d) and you could replace it with $2$1 where $2 is the second capturing group, (\d\d), and $1 is the first capturing group, (.*).

In my video, How to Bulk Rename Files Easily on Windows, I show how it is possible to reorder parts of a filename, add padding zeroes, and change date formats with just a few simple replacements.
