What File Renamer is
File Renamer is a free desktop app for batch renaming files on Linux and Windows. The project describes it as Free, Libre, Open Source Software and lists a GPL-3.0 license. Its documented workflow includes listing files, previewing proposed changes, and viewing renamed files. For portable use, the project wiki provides Linux and Windows installation instructions and says this method does not require root or administrator permission. The wiki also gives a pip installation command, `pip install io.github.flossapps.file-renamer`, and the launch command `file-renamer`. Portable installation is reported as tested with Fedora KDE Plasma Desktop, Ubuntu Desktop, and Windows 11. Ubuntu 24.04.4 LTS instructions call for installing `libxcb-cursor0`. Other desktop operating systems, including macOS, may work with pip, but that is untested. Its listed platform coverage is Linux and Windows, so users on other systems should check the installation details before relying on it.
