一棵樹專業版讓您可以在樹狀視圖上快速檢視所有驅動器/資料夾/檔案大小，以便輕鬆地進行手動磁片清理工作。

它會自動載入本地及網路磁碟、資料夾、檔案以及它們的大小（按從大到小次序排列），並且您可以對勾選資源批量地進行一些常用操作，例如移至資源回收筒、徹底刪除、移動/複製到其他地方。此外，它也為驅動器/檔案/資料夾提供一些特殊命令（如取得完整路徑）。所以，您可以使用一棵樹專業版來輕鬆地進行手動磁片清理工作。

實際上，它與 UNIX/Linux 的 du 命令類似，或您可以將它視作 Windows 上的具有圖形化使用者介面的 du 工具。

試用版限制：您只能查看前三層資源的大小。

# 檢視資源大小

啟動後，一棵樹專業版將載入所有驅動器以及佔用空間最小的驅動器的第一層資源。按一下某個資源（驅動器 / 資料夾）將載入它的第一層資源（檔案 / 資料夾）。
此外，您可以通過映射的網路磁碟來檢視遠端電腦上的資源大小樹（別忘記開啟“偏好”介面上的對應開關）。

# 執行操作

在一棵樹專業版中，您可以對勾選 / 高亮資源執行以下操作。
圖示 命令 適用於 工作模式 上下文功能表 快速鍵
刪除 徹底刪除 勾選資源 批量 右側清單 <Shift+Del>
回收站 移至資源回收筒 <Del>
複製到 複製到其他地方 <Ctrl+C>

取得完整路徑 取得完整路徑 <F4>
執行 / 開啟 執行 / 開啟 <按兩下>
顯示內容 顯示內容 <Alt+回車>

# 設置偏好

一棵樹專業版也為您提供一些自訂介面的選項，如樹狀視圖的字型、工具列位置及資料分隔符號（用於分隔資源的名稱和大小）、是否顯示光碟機及網路磁碟。並且您可以在存儲前預覽樹狀視圖字型及工具列位置的效果。

# 登錄許可證

如果您已支付許可證費用，將會通過 eMail 收到許可證金鑰！
請按下主介面<許可證>按鈕（倒數第三個）下面的“錄入許可證金鑰...”功能表項目以輸入或粘貼您許可證郵件中的金鑰。
注：如果註冊成功，您可以在“關於...”介面看到您的許可證資訊。

# 許可證金鑰丟失？

許可證金鑰丟失？不必擔心，您可以輕鬆地再次取得它。按下上述<許可證>按鈕下方的“許可證金鑰丟失？”功能表項目即可。

QuoteDownloaded, and registered was good, I am using a Hp 4 core 16 gig ram computer 64 bit. This software proved to be a big benefit as soon as I opened it up. My Logitech cam would not work, I reloaded the drivers several times to no avail. With this program I was able to find a backup of the original driver and restore it. Worked excellent.I was not aware of having the back up.This software shows all my internal, and external drives. I have 3 internal hard drives, and 1 external drive. It reads them all. I am using the latest ver of win 10.Thanks for this excellent giveaway. - By William Carter
