Adding Extra Model Paths
If you want to manage your model files outside ofComfyUI/models
, you may have the following reasons:
- You have multiple ComfyUI instances and want them to share model files to save disk space
- You have different types of GUI programs (such as WebUI) and want them to use the same model files
- Model files cannot be recognized or found
extra_model_paths.yaml
configuration file
Open Config File
For the ComfyUI version such as portable and manual, you can find an example file named Copy and rename it to
extra_model_paths.yaml.example
in the root directory of ComfyUI:extra_model_paths.yaml
for use. Keep it in ComfyUI’s root directory at ComfyUI/extra_model_paths.yaml
.
You can also find the config example file hereExample Structure
Suppose you want to add the following model paths to ComfyUI:extra_model_paths.yaml
file like below to let ComfyUI recognize the model paths on your device:
For the desktop version, please add the configuration to the existing configuration path without overwriting the path configuration generated during installation. Please back up the corresponding file before modification, so that you can restore it when you make a mistake.
D:\stable-diffusion-webui\
, you can modify the corresponding configuration to
Add Extra Custom Nodes Path
Besides adding external models, you can also add custom nodes paths that are not in the default path of ComfyUIPlease note that this will not change the default installation path of custom nodes, but will add an extra path search when starting ComfyUI. You still need to complete the installation of custom node dependencies in the corresponding environment to ensure the integrity of the running environment.
Desktop Python Environment
The desktop installation will create a Python virtual environment in your chosen installation directory, typically a hidden.venv
folder.
If you need to handle dependencies for ComfyUI plugins, you’ll need to do so within this environment. Using the system command line directly risks installing dependencies to the system environment, so please follow the instructions below to activate the appropriate environment.
How to use the Desktop Python environment?
You can use the built-in terminal in the desktop app to access the Python environment.

- Click the icon in the menu bar to open the bottom panel
- Click
Terminal
to open the terminal - If you want to check the Python installation location for the corresponding environment, you can use the following command
Unless you understand the meaning of your current operations, your actions may cause dependency issues in the corresponding environment. Please use this method with caution.
