GetShortPathName()
Непосредственно такой функции вроде нет, но можно изловчиться. Нарисовать там кнопку вручную и обрабатывать команды нажатия мышки на Caption Bar.

Эта версия работает под любым Delphi.
(Начиная с Delphi 2, это можно записать короче с использованием AnsiToOem и OemToAnsi.)
Здесь все просто.
function ConvertAnsiToOem(const S : string) : string;
{ ConvertAnsiToOem translates a string into the OEM-defined character set }
{$IFNDEF WIN32}
var
Source, Dest : array[0..255] of Char;
{$ENDIF}
begin
{$IFDEF WIN32}
SetLength(Result, Length(S));
if Length(Result) > 0 then
AnsiToOem(PChar(S), PChar(Result));
{$ELSE}
if Length(Result) > 0 then
begin
AnsiToOem(StrPCopy(Source, S), Dest);
Result := StrPas(Dest);
end;
{$ENDIF}
end; { ConvertAnsiToOem }
function ConvertOemToAnsi(const S : string) : string;
{ ConvertOemToAnsi translates a string from the OEM-defined
character set into either an ANSI or a wide-character string }
{$IFNDEF WIN32}
