This folder is empty

From Wikanual

The message

this folder is empty

gets displayed by INTERDUBS, when, well the folder has neither files or folders in it.

It can be supressed if the

IDXHTML_NOEMPTY_CONTENT

placeholder is being used instead of

IDXHTML_CONTENT

Since INTERDUBS now automatically considers a note as content this hack is probably no longer as needed as it used to be.
