OncePower is a free, open-source desktop utility designed for batch file renaming and organization. Built with Flutter, it provides a graphical interface for modifying large numbers of filenames without requiring regular expression knowledge. Users can replace, retain, insert, or remove text and apply prefixes, suffixes, numbering, and date-based naming. Its advanced mode supports regular expressions, formatting rules, and reusable presets. The application includes image and video previews to simplify visual file sorting. It can rename files using imported CSV data and modify file dates. An organization mode moves files into folders based on groups, types, or dates. Available for Windows and Linux, OncePower streamlines repetitive file management tasks.
