📂 File Renamer Pro

File Renamer Pro is a lightweight, blazing-fast batch file renaming tool built in C# (.NET 8).

Whether you need to organize a messy downloads folder or standardize thousands of assets, this tool lets you rename files in seconds using flexible templates, sequence numbers, date tokens, find/replace, and regular expressions.

Built with safety in mind, it runs in dry-run mode by default to let you preview changes before committing to them, and generates an undo log just in case.
