Batch Add not displaying possible folders

[Shanj]

I am logging in as admin, and I can add a single picture and edit it, as many times as I want.

But if I try to use the Batch Add Files feature, its page says
"Select the directory where you have uploaded your files."
but there is nothing there.
The text "Select the directory where you have uploaded your files." is not a link.
The page just follows this with
"Browsable interface (recommended)" which I have set to Yes.

I have searched this forum, and the documentation, but all I find is instructions telling me how to do it if I can see a list of folders to select, and I cannot see any.

Perhaps I've missed something I have to enable?

Did you use your FTP app to create a subfolder within the albums directory and upload pics to it in the first place?
