    Hi folks, here are some tools to play with your NKX files (and NICNT, NKR, NKS) whitout using Total Commander or Doucle Commander.

    NkxTool is 64-bit command-line utility for managing Native Instruments Kontakt archives. It acts as a specialized wrapper around the inNKX.wcx64 plugin, allowing you to list files, extract, and seamlessly pack libraries.

    Key Features
    - Multi-Format Support: Read and write .nkx (Audio/Samples), .nkr (Resources/Scripts), and .nicnt (Library Info) containers.
    - Smart Packing (Auto-Split): Automatically handles the strict 1.95 GB (2,090,000,000 bytes) size limit of the NKX format. If a source folder exceeds this limit, NkxTool automatically splits the output into _00.nkx, _01.nkx, etc.
    - Filelist Support: Pack archives dynamically using a text file containing relative paths (@filelist.txt), perfect for scripted audio conversions or selective repacking.
    - Update function for internal database: synced with system NativeAccess.xml with exotic / old libraries unique support.
    - Modern Architecture: Built with C# on .NET 10 (win-x64), completely standalone.

    NKXTool-UI is a lightweight desktop interface for NkxTool.exe, allowing to browse, create, and extract NKX and other NI archives format on Windows.

    The application focuses on a clean native workflow: pack a folder, pack from a @filelist.txt, unpack one or more archives, browse archive contents, switch light/dark theme, and run batch multi-pack operations from a single window.

    I will update my LiTE Converter script very soon, with full NKX unpacking/packing support and batch mode relying on NKXTool.

    I hope you will find these tools useful, feel free to leave some feedback here.
