File Renamer vs Filera

File Renamer is a free desktop application for batch renaming files on Linux and Windows. It is described as Free, Libre, Open Source Software under the GPL-3.0 license, with a free plan priced at free. Its documented workflow covers listing files, previewing changes, and viewing renamed files. The project wiki provides portable installation instructions for Linux and Windows and says this method needs no root or administrator permission. It also documents installation through pip with `pip install io.github.flossapps.file-renamer`, followed by the `file-renamer` command to start the app. Portable installation is reported as tested with Fedora KDE Plasma Desktop, Ubuntu Desktop, and Windows 11. Ubuntu 24.04.4 LTS requires `libxcb-cursor0`. Other desktop systems, including macOS, may work through pip but are untested.

Filera is a free batch file renaming tool for Linux, macOS, and Windows, designed to rename hundreds of files at once. A visual task pipeline offers find and replace, number sequences, dates, custom text, and case conversion, without scripting or regex. Before applying a rename, Filera shows old and proposed filenames side by side; files on disk remain unchanged until you apply the operation. Filters target files by name, type, date range, or size, and filtered files are skipped. Filera can walk directory trees and subfolders in one pass. You can rename files in place, copy renamed files to another directory, or move them. The app supports metadata-based renaming, but not regex renaming, folder renaming, or undoing changes. Built with Tauri and Rust, Filera is MIT licensed. Linux installation instructions list .deb packages for Debian and Ubuntu, and .rpm packages for Fedora and RHEL. Its Windows installer is not yet code-signed, so Windows Defender SmartScreen may show a warning.
