fetch models folder from other drive?

[chnisar515]

Hello Experts,

I am currently facing storage constraints on my primary 1TB SSD, which is nearly full. To free up space, I’ve decided to move my Models folder for ComfyUI to my second hard drive located in the E:\ drive. I do not have any other web UI tools like A1111 installed on this drive.

Here’s what I’ve done so far:
I copied the ComfyUI Models folder from its original location on the SSD to the following path: E:\My AI\comfyui\models. Then, from the ComfyUI portable directory (C:\ComfyUI_windows_portable\ComfyUI\models), I opened Command Prompt and ran the following command:

mklink /D models "E:\My AI\comfyui\models"

This created a symbolic link for the models folder within the ComfyUI directory. Afterward, I started ComfyUI and verified that all the data from my Models folder is correctly displayed.

My question is:
Will this method work consistently in all scenarios, or are there any potential issues or limitations I should be aware of?

Junctions are the way to go. The only thing I would change, is, to remove spaces in path and file names. Saves a lot of headaches in some cases,

If you do it that way, problems will occur when updating ComfyUI.
Instead, copy ComfyUI/extra_model_paths.yaml.example to ComfyUI/extra_model_paths.yaml and modify it for use.

Thank you for your reply, as i already gave you my new path of models folder so can you guide me how i can update it in ComfyUI/extra_model_paths.yaml ? i not a developer so please guide me.

     base_path: E:\My AI\comfyui\models

     loras: models/loras/
     upscale_models: models/upscale_models/
     vae: models/vae/

But I recommend that you remove the blanks in the path as mentioned above.
Blanks in paths often cause trouble.

I have removed the blanks from my path and now the path is E:\comfyuimodels\models

my extra_model_paths.yaml now looks like below

comfyui:
base_path: E:\comfyuimodels\models
is_default: true
checkpoints: models/checkpoints/
clip: models/clip/
clip_vision: models/clip_vision/
configs: models/configs/
controlnet: models/controlnet/
diffusion_models: |
models/diffusion_models
models/unet
embeddings: models/embeddings/
loras: models/loras/
upscale_models: models/upscale_models/
vae: models/vae/

but now when i start comfyui i am getting this error
