分享DirectoryExists需要用哪个头文件？
Determines whether a specified directory exists.
Unit
SysUtils
Category
file management routines
extern PACKAGE bool __fastcall DirectoryExists(constAnsiString Directory);
Description
Call DirectoryExists to determine whether the directory specified by the Name parameter exists. If the directory exists, the function returns true. If the directory does not exist, the function returns false.
If a full path name is entered, DirectoryExists searches for the directory along the designated path. Otherwise, the Name parameter is interpreted as a relative path name from the current directory.
上述是帮助文档，可是我在用这个函数的时候，总是出错，提示没有定义？

测试了，似乎不需要特别加入申明;空白文档加入即可，估计，LZ的函数名写错了
if (DirectoryExists("e:\\test"))
ShowMessage("test");
if (DirectoryExists("e:\\test"))
ShowMessage("test");

#include <vcl.h> 就可以了吧
