Link to share files

If the web GUI supported file URLs, I wouldn’t need to install another server in order to share files. I could download a file from the default folder through a URL like this:

http://127.0.0.1:8384/share/Default Folder/hello.txt

or from another folder through a URL like this:

http://127.0.0.1:8384/share/Folder Label/hello.txt

Would it be trivially easy to add this feature, or would it require a significant amount of code?
