请问如何判断目录是否存在?有没有WIN API

[lin1980]

if (GetFileAttribute(path) & FILE_ATTRIBUTE_DIRECTORY) //is directory

[FBL]

没有直接的API函数，你可以使用此函数：
GetFileAttributes（dir)
如果函数的返回值为0XFFFFFFFF，则表明目录不存在

[wukhai]

if(CFile::GetStatus(path,CFileStatus &fs))

[hyc1980]

PathFileExists
Determines whether a path to a file system object such as a file or directory is valid.

BOOL PathFileExists(
LPCTSTR pszPath
);

Parameters
pszPath
Full path of the object to verify.
Return Values
Returns TRUE if the file exists, or FALSE otherwise. Call GetLastError for extended error information.


Remarks
This function tests the validity of the path. It works only on the local file system or on a remote drive that has been mounted to a drive letter. It will return FALSE for remote file paths that begin with the UNC names \\server or \\server\share. It will also return FALSE if a mounted remote drive is out of service.
