fldrDialog SelectedPath   Environment GetFolderPath Environment SpecialFolder DesktopDirectory        If the SelectedPath property is set before showing the dialog box  the folder with this path will be the selected folder  as long as SelectedPath is set to an absolute path that is a subfolder of RootFolder  or more accurately  points to a subfolder of the shell namespace represented by RootFolder      MSDN - SelectedPath      The GetFolderPath method returns the locations associated with this enumeration  The locations of these folders can have different values on different operating systems  the user can change some of the locations  and the locations are localized     Re  Desktop vs DesktopDirectory  Desktop      The logical Desktop rather than the physical file system location     DesktopDirectory       The directory used to physically   store file objects on the desktop  Do   not confuse this directory with the   desktop folder itself  which is a   virtual folder     MSDN - Special Folder Enum  MSDN - GetFolderPath
