Cleanup not removing empty directories

We have a number of artifacts registered for our builds. These are located in different subfolders.

When clean up runs these artifacts are deleted. However the folders they were located in are left empty but are not deleted.

Is there a way to let Continua delete these empty directories or should we avoid putting artifacts in folders?

The cleanup should delete the folders, but sometimes deleting files/folders on windows just doesn’t work… we’ll look into it.
