windows api中没有提供现成的多层创建目录、删除目录。这里修改了部分代码实现递归创建目录、删除目录。

//删除目录

BOOL DeleteDirectory(char* sDirName)
{
    CFileFind tempFind;
    char sTempFileFind[200] ;

    sprintf(sTempFileFind,"%s//*.*",sDirName);
    BOOL IsFinded = tempFind.FindFile(sTempFileFind);
    while (IsFinded)
{
        IsFinded = tempFind.FindNextFile();

        if (!tempFind.IsDots())
  {
            char sFoundFileName[200];
            strcpy(sFoundFileName,tempFind.GetFileName().GetBuffer(200));

            if (tempFind.IsDirectory())
   {
                char sTempDir[200];
                sprintf(sTempDir,"%s//%s",sDirName,sFoundFileName);
                DeleteDirectory(sTempDir);
            }
            else
   {
                char sTempFileName[200];
                sprintf(sTempFileName,"%s//%s",sDirName,sFoundFileName);
                DeleteFile(sTempFileName);
            }
        }
    }
    tempFind.Close();
    if(!RemoveDirectory(sDirName))
{
        return FALSE;
    }
    return TRUE;
}

// 判断目录是否存在
BOOL FolderExists(CString s)
{
    DWORD attr;
    attr = GetFileAttributes(s);
    return (attr != (DWORD)(-1) ) &&
        ( attr & FILE_ATTRIBUTE_DIRECTORY);
}

// 创建目录

BOOL CreateDir(CString P)
{
    int len=P.GetLength();
    if ( len <2 ) return false;

    if('//'==P[len-1])
    {
        P=P.Left(len-1);
        len=P.GetLength();
    }
    if ( len <=0 ) return false;

    if (len <=3)
    {
        if (FolderExists(P))return true;
        else return false;
    }

    if (FolderExists(P))return true;



    CString Parent;
    Parent=P.Left(P.ReverseFind('//') );

    if(Parent.GetLength()<=0)return false;

    BOOL Ret=CreateDir(Parent);

    if(Ret)
    {
        SECURITY_ATTRIBUTES sa;
        sa.nLength=sizeof(SECURITY_ATTRIBUTES);
        sa.lpSecurityDescriptor=NULL;
        sa.bInheritHandle=0;
        Ret=(CreateDirectory(P,&sa)==TRUE);
        return Ret;
    }
    else
        return FALSE;
}
