Our verdict on reNamerX
reNamerX is a free, open-source desktop application for renaming multiple files with reusable rules. It suits users who need structured file changes rather than one-off edits, including text replacement, prefix or suffix changes, case transformations, sequential numbering, date and time rules, and regular-expression matching. Files or folders can be selected for processing, while live preview shows proposed changes before they are applied. The project is distributed under the MIT License.
Its strongest fit is rule depth for a free desktop tool. Regular-expression matching and replacement support more specific transformations, while reusable presets make repeatable naming workflows easier to maintain. Sequential numbering includes configurable formatting, and undo and redo provide a way to reverse rename operations. These capabilities make reNamerX a practical choice for organizing batches of files where naming logic matters more than a simple find-and-replace operation.
Platform coverage requires some care. The official site and installation guide describe Windows, macOS, and Linux, but the README says macOS and Linux support are forthcoming; Windows is the clearly supported platform in the project documentation. Folder renaming is not supported, and verified metadata-based renaming is limited, so users who depend on folder operations or deeper metadata workflows should choose a more specialized alternative. Pick reNamerX for free, rule-based batch renaming with previews and undo; avoid it when broad folder handling or mature multi-platform support is essential.
