Win32 API SHFileOperation

The win32 API SHFileOperation can be used to delete a whole directory or copy a directory from a path to another, below is an example:

// Delete the whole directory
BOOL DelDir(LPCTSTR lpszPath)
{
    char fPath[MAX_PATH];
    memset(fPath, 0, sizeof(fPath));

    strcpy(fPath, lpszPath);

    // Note : 目录不能以\或/结尾
    for (int i = strlen(fPath) - 1; i >= 0; i--) {
        if (fPath[i] == '\\' || fPath[i] == '/') {
            fPath[i] = 0;
        } else {
            break;
        }
    }

    SHFILEOPSTRUCT FileOp;
    FileOp.fFlags = FOF_NOCONFIRMATION;
    FileOp.hNameMappings = NULL;
    FileOp.hwnd = NULL;
    FileOp.lpszProgressTitle = NULL;
    FileOp.pFrom = fPath;
    FileOp.pTo = NULL;
    FileOp.wFunc = FO_DELETE;
    return SHFileOperation(&FileOp) == 0;
}

// Copy Directory or file, 注意字符串fromPath与toPath必须以"\0\0"结尾，
// 且目录的文件分割符是'\'，不是'/'
BOOL copy(LPCTSTR fromPath, LPCTSTR toPath)
{
    SHFILEOPSTRUCT FileOp;
    FileOp.fFlags = FOF_NOCONFIRMATION | FOF_NOCONFIRMMKDIR;
    FileOp.hNameMappings = NULL;
    FileOp.hwnd = NULL;
    FileOp.lpszProgressTitle = NULL;
    FileOp.pFrom = fromPath;
    FileOp.pTo = toPath;
    FileOp.wFunc = FO_COPY;
    return SHFileOperation(&FileOp) == 0;
}
