# ComfyUI Model Download Manager

A robust Java Swing application to identify and download missing models for ComfyUI workflows.

## Features
- **Advanced JSON Parsing**: Recursively scans ComfyUI JSON workflows (including subgraphs and `widgets_values`) for model filenames.
- **Model Metadata Support**: Detects and uses embedded model download metadata (URLs, directories).
- **Download Manager**:
    - **Resume Capability**: Uses HTTP Range requests to resume interrupted downloads.
    - **Pause/Resume/Stop**: Full control over the download queue.
    - **Overwrite Protection**: Prompts before overwriting existing local files.
    - **Real-time Status**: Shows download speed (MB/s) and per-file progress.
- **Intelligent Sorting**: Automatically infers the correct subfolder (e.g., `checkpoints`, `loras`, `vae`) based on node types.
