如何检查带空格的目录或文件名是否存在

@echo off
if not exist "C:\"Documents and Settings"\box\putty\file"
( 
echo hello
)
pause

错误：

'and' is not recognized as an internal or external command,
operable program or batch file.
hello
Press any key to continue . . .

@echo off
if not exist "C:\Documents and Settings\box\putty\file" ( 
echo hello
)
pause

确保" (

之间有空格
