The RelativeName property is read-only. The relative name of the object does not include the folder being referred by the ExploreFromHere property. The FullName property gets the full path for the file or folder. Use Folder property to check whether the File object contains a file or a folder.  Use the Name to get the displayed file/folder's name. For instance, if the  ExploreFromHere' is 'C:\TEMP' and you browse in that folder to 'C:\TEMP\TEXT\OWN\abc.txt' the RelativeName property returns '\TEXT\OWN\abc.txt', so not the full name and path but the relative path to ExploreFromHere property.
