TIEPortableDevices.ActiveFolderID
 
Declaration
property ActiveFolderID : WideString; (read/write)
Description
Returns the ID of the folder that is currently being read (the source of 
Objects). I.e. if you have called 
NavigateToFolderPath then 
ActiveFolderID will be the Folder ID that you passed.
You can also specify a folder ID to navigate to that folder on the 
active device.
ActiveDeviceID := sFolderID;
Is the same as:
NavigateToFolderPath( ActiveDeviceID, sFolderID);  
If '' is returned then the active folder is the device root
// Display the current folder
edtCurrentFolder.Text := fPortableDevices.LookupItemFriendlyName( fPortableDevices.ActiveFolderID );
