ReNamer

Advanced batch file renaming for Windows

ReNamer is a Windows utility for changing file and folder names in bulk, aimed at users who want more control than the standard rename option provides. It is well suited to organizing photo collections, document folders, media libraries, archives, or any large group of files that needs a consistent naming pattern.

The program works through a rule-based system. You add the files or folders you want to process, build one or more renaming rules, then review the proposed results before applying them. The preview panel is especially useful, as it lets you spot mistakes before any names are actually changed.

For common tasks, ReNamer can add prefixes or suffixes, modify extensions, change letter case, remove unwanted text, and strip out selected parts of a filename, including content inside brackets. For more advanced use, it supports saved rule sets, Regular Expressions, Pascal Script rules, Unicode filenames, and metadata-based renaming. Its metadata support includes image-related tags such as EXIF, TIFF, and IPTC fields like caption, headline, location, and city, which can be helpful for photographers or users managing structured image libraries.

The interface is plain but practical. Rules are managed in one area, while the file list and rename preview sit below, making the workflow easy to understand once you know what each rule does. There is also a getting started guide, Windows context menu integration, and configuration options for users who want to adapt the tool to their habits.

The main drawback is that ReNamer can feel excessive for someone who only needs to rename a few files occasionally. Its many rule types and scripting options may be more than casual users need. However, for anyone who regularly handles batches of files and wants predictable, repeatable naming control, ReNamer is a capable and flexible choice.
