This check box makes it possible to load and rebuild (part of) a folder structure in the ITP/MDK Repository. If this check box is checked the subfolders of the selected folder, and their content are selected as well. Note that this is the only way to load folders into the ITP/MDK Repository. The load process skips empty folders or folders that contain no files that comply with the mask. In short: if a folder appears empty in the Files box it will be skipped.
