Thanks! That's such an obvious answer that I feel foolish to not have noticed it before. 😳
I had the examples in my app, but instead of looking through the folders, I tried typing things like "qr" or "url" into the search field at the top of the file manager, but I didn't find it. Now that I know I have that program in my files, I understand the search isn't recursive, it only filters the current list.
Are there any plans to make the file manager search recursive?
