The DROPEXT sample demonstrates how to extend the drag-and-drop context  
menu. 
 
To test DROPEXT.DLL, you must: 
 
1. Build DROPEXT.DLL. 
 
2. Copy DROPEXT.DLL to the system directory (for example, c:\windows\system). 
 
   -or- 
 
   Modify DROPEXT.REG file to points to a fully qualified path to the DLL. 
 
3. Run the command: regedit dropext.reg. 
 
4. Use the right mouse button to drag a file from one folder to another. 
   You will see additional menu items for the drop operation.
