文件完整路径超出MAX_PATH，无法用代码删除

[凌乱哥]

首先声明文件确实存在且路径正确，核对了好几遍，文件完整路径如下：

C:\Users\XX\AppData\Local\Temp\ts_download\[e-mail]
\B512771D40A2DF1FD35216E710E6204C1530D8D7\20171024\AppDomain-com.netease.cloudmusic
\Library\Application Support\321\0459d8a2-02cd-4478-9d53-f5687f29320f\shaders\src\starry_sky
\default_varying.def.sc

全长261个长度，比这长的也有，就拿它举例子

用CFile::Remove能捕获到异常：包含错误的路径


用DeleteFile函数则失败，GetLastError返回3

// MessageId: ERROR_PATH_NOT_FOUND
//
// MessageText:
//
// The system cannot find the path specified.
//
#define ERROR_PATH_NOT_FOUND             3L

而且这个文件全路径还无法用GetShortPathName获取短路径，GetLastError也是返回3
百度搜索的都是用cmd，那用代码该怎么实现删除超长路径文件

补充一下，我的电脑是win10，64位 用Windows自己的删除功能或者彻底删除功能是可以直接有效删除的

把文件名 分成 2 段， 用 前面的 来 设置 当前目录，后面 是 文件名。不知道 行不行 ？

call the Unicode version of the function and prepend "\\?\" to the path 这是指哪个函数的Unicode版本，CFile::Remove还是DeleteFile 加"\\?\"是加到前面还是后面，有没有例子

是Unicode工程，调的也是DeleteFileW，删除不了

加了\\?\后，2个函数都可以删除了，厉害了
