我自己写的一个每日自动更新小说的软件就是使用这个函数修改文件夹的时间以方便按照最后更新时间进行排序
同样是win7x64,我就没有碰到任何问题
检查你自己的代码吧,估计是FILETIME的问题
To prevent file operations using the given handle from modifying the last access time, call SetFileTime immediately after opening the file handle and pass a FILETIME structure whose dwLowDateTime and dwHighDateTime members are both set to 0xFFFFFFFF.
