Ahoy,
testing HFS, maybe, i encounter the same problem.
One time i use drag and drop, second time i add a folder via the context menu from the file explorer.
I am just testing HFS, so i don't have a solution for you.
For the moment i use only the context menu to add a folder.
Another strange thing :
HFS is running 2 days without a problem, but since yesterday, after some time, i cannot open my page in the internet explorer at home. This happened again 2 times. So, no warp any more
From work it was no problem ...
