comfyui-file-uploader

comfyui-file-uploader

Tiny custom node that adds drag & drop file upload to any hosted ComfyUI where you don't have shell access.

What it does

Adds a node File Uploader (category utils/io) with:

• subfolder input (STRING, default fonts): subdirectory inside ComfyUI's input/ directory.
• file dropdown: lists files currently in input/<subfolder>/.
• Upload button: opens browser file picker, uploads the selected file to input/<subfolder>/, refreshes the dropdown.

Outputs:

• file_path: absolute path to the chosen file (e.g. for nodes that take a file path)
• folder_path: absolute path to the subfolder (e.g. for CR Font File List which wants a folder)
• filename: just the filename

Install

Drop the whole folder into your ComfyUI custom_nodes/ directory:

ComfyUI/custom_nodes/comfyui-file-uploader/
    __init__.py
    nodes.py
    web/js/upload-widget.js

Restart ComfyUI. Refresh the browser.

Usage for the Scania font case

1. Add File Uploader node.
2. Set subfolder to fonts (or whatever you want).
3. Click "📁 Upload file", pick ScaniaOfficeHeadline-Bold.ttf.
4. Wire folder_path output into CR Font File List's folder path input. Or wire file_path into a node that takes a direct font file path (S4Tool-Text etc.).

Endpoints

• POST /file_uploader/upload — multipart file + subfolder
• GET /file_uploader/list?subfolder=... — returns {files: [...]}

Notes

• Files land inside ComfyUI/input/. Path traversal (../) is blocked.
• On RunPod / hosted setups: input/ is usually under /workspace/ or wherever ComfyUI's working dir is. Survives across pod restarts only if that path is on persistent storage.
• No file size limit enforced here. Your hosting's reverse proxy may have one (typically 100MB+).
