I have three sets of Stable Diffusion ui installed on my computer:

• a1111 webui
• comfyui
• 秋叶整合包( An integrated package of SD webui)

There are usually two methods:
Mklink and Command line parameters.

1. Mklink (symbolic link)

It is similar to a folder pointer or shortcut, which allows the model folders of each SD UI, such as models, to point to the same centrally stored model folder.

mklink /d C:\XXX\A D:\XXX\B

D:\ai\models\sd\webui_using

Some commonly used model files are classified under this folder:
