What did you do?

Compiled this program which is a very simple webdav server to serve a directory over webdav.

I ran this in a command window with webdavd.exe -p 8081 -d c:\path\to\test\dir

I then pointed windows explorer at it by putting in the url \\localhost:8081\. Windows explorer sees all the directories but none of the files and an attempt to click on a directory gives a permissions error.

Source directory

Directory when viewed via the webdav server. I expected to see all the files and the folders here.

And the error message you get when clicking on a directory

And here is the server running in the cmd window

I originally discovered this while trying out rclone serve webdav which has exactly the same problem.
