Hi Paul,
you have to create some registry values and keys under
HKEY_CLASSES_ROOT:

var
Reg : TRegistry;

begin
   Reg:=TRegistry.Create;
  Reg.RootKey:=hKey_Classes_Root;
  Reg.OpenKey('.ext',true);       //  create key for file extension
  Reg.WriteString('','MyExtension');       // Write alias
  Reg.CloseKey;                    // Close this key before opening
another
  Reg.OpenKey('MyExtension,true);        // Create alias key
  Reg.WriteString('','My registered file type'); // Write description
  Reg.CloseKey;                    // Close this key before opening
another
  // The associated exe file is stored in the subkey
/shell/open/command
  Reg.OpenKey('MyExtension\shell\open\command',true);
  Reg.WriteString('','c:\PathToMyApp\myapp.exe %1');      // Write the
associated exe command string
  // This string contains path and filename of exe file as well as
parameter
  // variable for opening, usually %1.
  Reg.Free;
end;

Hope this helps
