MFC下对文件及文件夹的操作(复制、剪切、删除、创建文件夹，写文件)

一、文件夹的创建

void CFileOperationDlg::OnButtonMakeFolder() 
{
    // TODO: Add your control notification handler code here
    UpdateData(TRUE);
    CFileFind m_sFileFind;

    if (!m_sFileFind.FindFile(m_FolderName))
    {
        CreateDirectory(m_FolderName,NULL);
    }
}

二、文件的创建

void CFileOperationDlg::OnButtonMakeFile() 
{
    // TODO: Add your control notification handler code here
    UpdateData(TRUE);
    CFile m_sFile;
    m_sFile.Open(m_FolderName + TEXT("\") + m_FileName,CFile::modeCreate|CFile::modeNoTruncate|CFile::modeReadWrite|CFile::shareDenyWrite);
    m_sFile.SeekToEnd();
    m_sFile.Close();
}

三、文件夹的复制(包括文件的复制)

void CFileOperationDlg::OnButtonCopy() 
{
    // TODO: Add your control notification handler code here
    UpdateData(TRUE);
    CString m_strDestPath;
    m_strDestPath = "D:\TestMyself\FileOperation\Debug";
    CString m_strSrcPath = "D:\TestMyself\FileOperation\VISTA";
    CopyDirectory(m_strSrcPath,m_strDestPath);
}

BOOL CFileOperationDlg::CopyDirectory(CString strSrcPath,CString strDestPath)
{
    CFileFind m_sFileFind;
    if (strSrcPath.IsEmpty())
    {
        OutputDebugString("源文件名为空，无法进行拷贝!");
        return FALSE;
    }
    if (!m_sFileFind.FindFile(strDestPath))
    {
        CreateDirectory(strDestPath,NULL);//创建目标文件夹
    }
    CFileFind finder;
    CString path;
    path.Format("%s/*.*",strSrcPath);
    //AfxMessageBox(path);
    BOOL bWorking = finder.FindFile(path);
    while (bWorking)
    {
        bWorking = finder.FindNextFile();
        //AfxMessageBox(finder.GetFileName());
        if (finder.IsDirectory() && !finder.IsDots())//是文件夹 而且 名称不含 . 或 ..  
        {
            CopyDirectory(finder.GetFilePath(),strDestPath+"/"+finder.GetFileName());//递归创建文件夹+"/"+finder.GetFileName()  
        }
        else
        {//是文件，则直接复制
            //AfxMessageBox("复制文件"+finder.GetFilePath());//+finder.GetFileName()  
            CopyFile(finder.GetFilePath(),strDestPath+"/"+finder.GetFileName(),FALSE);
        }
    }

    return TRUE;
}

CString CFileOperationDlg::GetFilePath()
{
    CString m_FilePath;

    GetModuleFileName(NULL,m_FilePath.GetBufferSetLength(MAX_PATH+1),MAX_PATH);
    m_FilePath.ReleaseBuffer();

    int m_iPosIndex;
    m_iPosIndex = m_FilePath.ReverseFind('\');
    m_FilePath = m_FilePath.Left(m_iPosIndex+1);

    return m_FilePath;
}

CString CFileOperationDlg::GetFileName()
{
    CString sFileName;
    
    sFileName = CTime::GetCurrentTime().Format("%Y-%m-%d") + TEXT(".log"); 
    
    return sFileName; 
}

四、文件夹的删除

BOOL CFileOperationDlg::DeleteFolder(LPCTSTR lpszPath)
{
    int nLength = strlen(lpszPath);
    char *NewPath = new char[nLength + 2];
    strcpy(NewPath,lpszPath);
    NewPath[nLength] = '';
    NewPath[nLength + 1] = '';
    SHFILEOPSTRUCT FileOp;
    ZeroMemory((void*)&FileOp,sizeof(SHFILEOPSTRUCT));
    FileOp.fFlags = FOF_NOCONFIRMATION;
    FileOp.hNameMappings = NULL;
    FileOp.hwnd = NULL;
    FileOp.lpszProgressTitle = NULL;
    FileOp.pFrom = NewPath;
    FileOp.pTo = NULL;
    FileOp.wFunc = FO_DELETE;
    return SHFileOperation(&FileOp) == 0;
}

五、文件夹的移动（剪切）

BOOL CFileOperationDlg::MoveFolder(LPCTSTR lpszFromPath,LPCTSTR lpszToPath)
{
    int nLengthFrm = strlen(lpszFromPath);
    char *NewPathFrm = new char[nLengthFrm + 2];
    strcpy(NewPathFrm,lpszFromPath);
    NewPathFrm[nLengthFrm] = '';
    NewPathFrm[nLengthFrm + 1] = '';
    SHFILEOPSTRUCT FileOp;
    ZeroMemory((void*)&FileOp,sizeof(SHFILEOPSTRUCT));
    FileOp.fFlags = FOF_NOCONFIRMATION ;
    FileOp.hNameMappings = NULL;
    FileOp.hwnd = NULL;
    FileOp.lpszProgressTitle = NULL;
    FileOp.pFrom = NewPathFrm;
    FileOp.pTo = lpszToPath;
    FileOp.wFunc = FO_MOVE;
    
    return SHFileOperation(&FileOp) == 0;    
}

六、文件写操作

void CFileOperationDlg::OnButtonOk() 
{
    // TODO: Add your control notification handler code here
    UpdateData(TRUE);
    try
    {
        CFile m_sFile;
        CFileFind m_FileFind;
        CString m_sErrorMessage;
        //CString m_sFileName = GetFileName(); 
        //CString m_sFilePath = GetFilePath(); 
        CString m_sCurrentTime = (CTime::GetCurrentTime()).Format("%Y-%m-%d %X");

        if (!m_FileFind.FindFile(m_FolderName))
        {
            CreateDirectory(m_FolderName,NULL);
        }
         m_sFile.Open(m_FolderName + TEXT("\") +m_FileName,CFile::modeCreate |CFile::modeNoTruncate| CFile::modeReadWrite |CFile::shareDenyWrite); 

         m_sFile.SeekToEnd();

         if (sizeof(TCHAR) == sizeof(WCHAR))
         {
             WORD wSignature = 0xFFFF;
             m_sFile.Write(&wSignature,2);
         }

         m_sErrorMessage = TEXT("*******************") + m_sCurrentTime + TEXT("*******************")+TEXT("
") ;
         m_sFile.Write(m_sErrorMessage,m_sErrorMessage.GetLength()*sizeof(TCHAR));

         m_RichText += TEXT("
");
         m_sFile.Write(m_RichText,m_RichText.GetLength()*sizeof(TCHAR));
         m_sFile.Close();
    }
    catch(CFileException fileException) 
    { 
        return ; 
    }
    
}

以上代码测试通过！！
