QDoc overwrite html files

Question

I use qdoc for creating code documentation. I can generate my documents from comments, but I need to delete the old generated files before replacing them with new ones. As an illustration, when I execute the command qdoc project.qdocconf, it gives me the error message: "(qdoc) error: Output directory './html' exists but is not empty." How can I tell qdoc to overwrite html directory?

Note:

• I'm using qdoc 6.5.1

What did I do?

• I previously read the qdoc documentation, but unfortunately, it wasn't much help to me.
