File Renamer

File Renamer is a desktop application for batch-renaming files on Linux and Windows. It presents a workflow for listing files, previewing proposed changes, and viewing the renamed results. The project describes itself as Free, Libre, Open Source Software and uses the GPL-3.0 license. Its free plan is listed as free. The project wiki provides portable installation instructions for both Linux and Windows, with no root or administrator permission required. Those portable instructions are reported as tested with Fedora KDE Plasma Desktop, Ubuntu Desktop, and Windows 11. The wiki also documents installation through pip with `pip install io.github.flossapps.file-renamer`, followed by the `file-renamer` command to launch it. Ubuntu 24.04.4 LTS users are instructed to install `libxcb-cursor0`. Other desktop systems, including macOS, may work through pip, but are untested.

File Renamer focuses on batch renaming with a documented preview flow. Its free, open-source distribution and portable Linux and Windows instructions make installation details clear, while untested systems require caution.

It suits users who need batch file renaming on Linux or Windows, especially those wanting a preview and portable installation. Open-source users may also value its FLOSS model and GPL-3.0 license.
