Simple Folder Explorer

Using Streamlit
1

I was looking for a folder browser but could not find anything built-in. As others must need a solution for this, I’m sharing my simple folder browser. Single click selects folder. Double click opens folder. I’m sure that others have come up with better solutions. Please share yours by replying to this post.
