DSC1790.jpg, DSC1791.jpg, DSC1792.jpg… We’ve all stared at a folder of meaningless file names and dreaded fixing them by hand. Bulk Rename Utility (BRU) is the Windows tool that turns that chore into a few clicks — and it can batch-rename thousands of files in seconds.

What it is

Bulk Rename Utility is a lightweight, blazing-fast file renamer for Windows. It began as a freeware Visual Basic tool, then was completely rewritten in C++ to be robust and efficient — it can handle folders with well over 100,000 entries without breaking a sweat, while keeping a tiny memory footprint.

It’s free for personal, private use at home. Using it inside a business or for commercial purposes requires a commercial license.

What makes it powerful

The interface looks dense at first, but that density is the point: every renaming rule you could want, in one panel, with a live preview before anything is committed.

  • Add, remove, replace, insert text anywhere in a name.
  • Change case, strip digits or symbols, and prepend/append text or the parent folder name.
  • Auto-number files with highly flexible rules.
  • EXIF photo renaming — turn dsc1790.jpg into NewYork1.jpg using “date taken”, resolution, and other embedded metadata.
  • MP3 ID3 tag renaming and renaming by Windows file properties (video length, width, height, publisher, and 100+ attributes).
  • Add date/time stamps and change files’ created/modified/accessed timestamps.

For the power users

  • Regular expressions and even JavaScript conditions for surgical control.
  • Rename from a CSV list, filter with wildcards or name/path length.
  • Create an Undo batch file and log every renaming action.
  • Directory recursion to process all sub-folders at once.
  • Optional “Bulk Rename Here” entry in Windows Explorer’s right-click menu.
  • 32-bit and 64-bit, a portable no-install version, and Dark Mode.

Save your renaming criteria as favorites so recurring jobs take one click next time.

Compatibility

BRU runs on essentially every Windows version — Windows 11, 10, 8, 7, Vista, XP, and Windows Server releases. The current release is version 4.

Who it’s for

Photographers cleaning up shoots, developers normalizing asset names, anyone wrangling downloads or media libraries — if you rename files in batches, BRU pays for itself the first time you use it (and it’s free at home).

A good utility disappears into your workflow. Learn Bulk Rename Utility once, and you’ll never dread a messy folder again.
