Original GitHub issue: https://github.com/DominikDoom/a1111-sd-webui-tagcomplete/issues/132

After I mklink 'extensions' folder to somewhere else, 'Gradio app' report an error as follow:
ValueError: File cannot be fetched: extensions/ANY OF THE JS FILE FROM ABOVE. All files must contained within the Gradio python app working directory, or be a temp file created by the Gradio python app.
mklink error

And here is as far as i can dig into it, unable to understand it.

Right now I can cancel that mklink to let 'extensions' work again, but Im still a little bit curious any way to fix Gradio? Update that web app program?

That is sadly a hard limitation by Gradio. They only allow files in the root folder of the app to be fetched for security reasons, since it is essentially a local server and not doing so would allow bad actors to potentially get to any file on your PC (at least as soon as you share the webui on the local network or even the internet). Since it appears they follow the actual symlink location instead of treating it as the "fake" path, these files are now all outside of the root folder, which blocks the request.

There's no proper way to get around that with symlinks as far as I know. Maybe true junctions instead of symlinks would work, but I haven't tried that.
