Description

Ant Renamer is a free Windows utility for renaming many files and folders in one operation. It was created by Belgian developer Antoine Potten, and the name combines the author's surname with the program's purpose: a focused renamer rather than a broad file manager.

The program changes file and folder names without modifying the file contents, which makes it suitable for photo collections, downloads, archives, music folders and other libraries that need consistent naming. Source code is available, and the application has long been offered in both installer and portable ZIP forms.

Ant Renamer Features

Ant Renamer is built around rename actions that can be stacked before they are applied. You can add a group of files, choose actions such as inserting text, replacing strings, changing case or adding numbers, then preview the result before committing the operation.

The tool is useful because it covers both simple cleanup and more advanced batch rules. Unicode file-name support, regular expressions, extension changes and random-name generation give it enough range for technical users, while the action list keeps common jobs approachable.

  • Batch renaming for files and folders on Windows.
  • Unicode file-name support on Windows NT-based versions.
  • String insertion, string replacement, case conversion and extension changes.
  • Numbering, random name creation and regular-expression based rename rules.
  • Portable ZIP and installer packages, with interface translations for multiple languages.

Ant Renamer Review

Ant Renamer succeeds because it keeps a potentially risky job visible before anything is written. The preview step is the key detail: it lets you check generated names, correct an action order, or remove a file from the batch before a large folder gets renamed.

The interface is plain but efficient. Most users can add files, select the Actions area and build a rename sequence quickly, while more advanced users can combine several actions into a single repeatable batch for messy collections or imported media.

That action-based model is also safer than trying to rename files manually in Explorer when the same pattern needs to be applied hundreds of times. Ant Renamer gives you one place to define the rule, review the proposed result and apply it consistently across the entire selection.

The small installer and portable archive make Ant Renamer easy to keep as a utility rather than a permanent desktop application. Users who still need very old Windows 95 compatibility should look for older Ant Renamer releases, because newer versions target later Windows generations.
