Nomina
What it is
Nomina is a free desktop app for renaming files and folders in batches. Its live preview lets users review proposed changes before committing them, and its rule engine covers prefixes, suffixes, text replacement with optional regular expressions, removal, slicing, case changes, numbering, and extension changes. The app can scan folders recursively, filter results, accept drag-and-drop items, and load paths from the clipboard. It flags invalid characters, name conflicts, and reserved names, and can undo the last rename batch. Users can save, import, and export rule presets as JSON files, and optionally clean metadata while renaming. The interface supports English and Persian, including right-to-left layout, alongside dark and light themes. The README describes Nomina as having no telemetry. Prebuilt downloads are listed for Windows x64, Linux x64 and ARM64, and macOS Apple Silicon; the macOS build is stated to run on Intel via Rosetta 2. Listed desktop requirements are Windows 10/11, Linux with GTK 3 and WebKit2GTK 4.1, or macOS 11 or newer. Running from source requires Python 3.10+. Nomina is MIT licensed and has a free plan.
