CPMM

What CPMM is
CPMM is a free, open-source Windows manager for Cyberpunk 2077 mods and core game settings. It supports standard installation as well as advanced or manual methods, including mods placed in folders such as mods, dlc, bin, engine, r6, and plugins. ZIP and 7-Zip archives are supported, while password-protected archives are ignored. An archive can include modmanager.json metadata with a mod name, author, version, category, and priority. Users can choose a custom backup path, and the manager can launch the game with optional executable arguments. Multiple language packages are available. CPMM is built with C# and WPF on .NET 5; the standard package requires the .NET 5 x64 runtime unless a self-contained package is used. The project is distributed through Nexus Mods and is licensed under GNU GPL-3.0. Its maker describes it as beta software, warning that some functions may not work. File deletion may not always work, so changes require caution.
