API文件(夹)操作总结：拷贝、删除等

//删除文件或者文件夹
bool DeleteFile(string strPath)
{
    int nLen = strPath.length();
    char* pPath = new char[nLen+2];
    strcpy(pPath,strPath.c_str());
    pPath[nLen+1]='\0';

    SHFILEOPSTRUCT FileOp={0};
    FileOp.fFlags = //FOF_ALLOWUNDO |   //允许放回回收站
        FOF_NOCONFIRMATION |  //不出现确认对话框
        FOF_NOERRORUI; //不出现错误对话框
    FileOp.pFrom = pPath;
    FileOp.pTo = NULL;      //一定要是NULL
    FileOp.wFunc = FO_DELETE;    //删除操作

    bool bResult = (SHFileOperation(&FileOp) == 0);
    delete []pPath;
    return bResult;
}

//复制文件或文件夹
bool CopyFile(string strFrom,string strTo)
{
    int nFromLen = strFrom.length();
    int nToLen = strTo.length();
    char* pFrom = new char[nFromLen+2];
    char* pTo = new char[nToLen+2];
    strcpy(pFrom,strFrom.c_str());
    strcpy(pTo,strTo.c_str());
    pFrom[nFromLen+1]='\0';
    pTo[nToLen+1]='\0';

    SHFILEOPSTRUCT FileOp={0};
    FileOp.fFlags = FOF_NOCONFIRMATION|   //不出现确认对话框
        FOF_NOCONFIRMMKDIR ; //需要时直接创建一个文件夹,不需用户确定
    FileOp.pFrom = pFrom;
    FileOp.pTo = pTo;
    FileOp.wFunc = FO_COPY;
    bool bResult = (SHFileOperation(&FileOp) == 0);
    delete []pFrom;
    delete []pTo;
    return bResult;
}

//移动文件或文件夹
bool MoveFile(string strFrom,string strTo)
{
    int nFromLen = strFrom.length();
    int nToLen = strTo.length();
    char* pFrom = new char[nFromLen+2];
    char* pTo = new char[nToLen+2];
    strcpy(pFrom,strFrom.c_str());
    strcpy(pTo,strTo.c_str());
    pFrom[nFromLen+1]='\0';
    pTo[nToLen+1]='\0';

    SHFILEOPSTRUCT FileOp={0};
    FileOp.fFlags = FOF_NOCONFIRMATION|   //不出现确认对话框
        FOF_NOCONFIRMMKDIR ; //需要时直接创建一个文件夹,不需用户确定
    FileOp.pFrom = pFrom;
    FileOp.pTo = pTo;
    FileOp.wFunc = FO_MOVE;

    bool bResult = (SHFileOperation(&FileOp) == 0);
    delete []pFrom;
    delete []pTo;
    return bResult;
}

//从命名文件或文件夹
bool ReNameFile(string strFrom,string strTo)
{
    int nFromLen = strFrom.length();
    int nToLen = strTo.length();
    char* pFrom = new char[nFromLen+2];
    char* pTo = new char[nToLen+2];
    strcpy(pFrom,strFrom.c_str());
    strcpy(pTo,strTo.c_str());
    pFrom[nFromLen+1]='\0';
    pTo[nToLen+1]='\0';

    SHFILEOPSTRUCT FileOp={0};
    FileOp.fFlags = FOF_NOCONFIRMATION;   //不出现确认对话框
    FileOp.pFrom = pFrom;
    FileOp.pTo = pTo;
    FileOp.wFunc = FO_RENAME;

    bool bResult = (SHFileOperation(&FileOp) == 0);
    delete []pFrom;
    delete []pTo;
    return bResult;
}

SHFileOperation操作，如果是相对路径需要后面两个'\0',如"..\\x.xml\0",包括自身的\0
