   I haven't found any code example to add the StringData structure.   
   Looks like you have to create the .lnk file by yourself.   
      
   IShellLinkA::SetRelativePath doesn't seem to do this:   
   https://learn.microsoft.com/en-us/windows/win32/api/shobjidl_cor   
   /nf-shobjidl_core-ishelllinka-setrelativepath   
      
      
   This is from the LNK file format:   
      
   2.1.1 LinkFlags   
   The LinkFlags structure defines bits that specify which shell link structures   
   are present in the file format after the ShellLinkHeader structure.   
      
   HasRelativePath (0x00000008)   
   The shell link is saved with a relative path string. If this bit is set, a   
   RELATIVE_PATH StringData structure (section 2.4) MUST be present   
      
   2.4 StringData   
   RELATIVE_PATH: An optional structure that specifies the location of the link   
   target relative to the file that contains the shell link. When specified, this   
   string SHOULD be used when resolving the link.   
      
   ...   
   Example:   
   Because HasRelativePath is set, the RELATIVE_PATH StringData structure   
   follows:   
      
       CountCharacters: (2 bytes), 0x0007 Unicode characters.   
       String (14 bytes), the Unicode string: ".\a.txt".   
      
   ciao...
