WPObject and WPFileSystem are the only system classes that contribute Details fields to the Sort dialog of the Settings notebook. User-defined class may introduce their own Details fields as sort criteria.
The sort class for a particular container determines what class' sort Details fields will appear as active sort criteria on the container's Sort dialog of the Settings page. The default sort class for all containers is WPFileSystem. This sort class can be manually changed via the container's Settings page, and it can also be programmatically changed by using wpSetFldrSortClass.
The wpSetFldrSortClass and wpQueryFldrSortClass methods are needed to set both the Always maintain sort order checkbox on a container's Sort dialog, as well as the chosen sort field.
Note: The sort methods are explained in Folder Related Methods.
