As an alternative to 
Filesystem drag-and-drop, you can link files and folders into a project. This
            method of linking resources lets you include files in your project, even if they need to
            reside in a specific place on your filesystem (because of a restrictive source control
            system, for example).
         
To add a linked resource to a project in the Project Explorer view:
         
         
         
            - 
               Right-click on a project, and then select either  or . 
               The New File or New Folder dialog appears. 
               
            
- 
                In the File Name or Folder Name
                  field, type a new name for the file or folder. 
               
            
- 
                Click Advanced >>, and enable
                  either the Link to file in the file system or
                  Link to folder in the file system option. 
               
            
- 
               Type the full path to the file or folder, or click
                  Browse… to select a specific file or
                  folder. 
               
            
- 
               Click Variables… to define any path variables
                  for use in the file or folder path. 
               
            
- 
               Click OK. 
               
            
- 
               Click Finish to link the file or folder into your
                  project.
