進階電腦操作方法_CMD

1. 關於 Windows 檔案系統
   • 是一個 階層式 的結構
   • 檔案總管(File Explorer)
     • 點選 本機 可以看到目錄和磁碟機
   • 磁碟機 / 根目錄 (Disk/Root Folder)
     • 用 磁碟機代號 來區隔電腦中的儲存空間
     • C: / D: / E: / F: /
   • 目錄 (Folder) 與檔案 (File)
     • 資料夾 <-> 目錄
     • 路徑( / )
   • 可執行檔(Executable File)
     • .exe

撰寫GUI設計流程

2. 元件（按鈕、文字方塊、選單）加入視窗中
3. 事件處理函示（event handler)：使用者互動時的觸發行為
