Flut Renamer is a cross-platform bulk file renaming application built with Flutter. It allows users to rename multiple files and directories through configurable rules. Operations include inserting, replacing, removing, rearranging, and truncating filename text. Sequential numbering supports customizable starting values, increments, prefixes, and suffixes. Metadata-based rules can incorporate file dates, sizes, photo EXIF information, and audio tags. The application also supports letter case conversion, Chinese character conversion, and transliteration. Multiple rules can be combined and reordered, with previews showing the resulting filenames before changes are applied. Users can filter files, rename selected entries, and save reusable configurations as YAML. Flut Renamer supports Windows, macOS, Linux, Android, and iOS.
