一棵树专业版让您可以在树状视图上快速查看所有驱动器/目录/文件大小，以便轻松地进行手动磁盘清理工作。

它会自动载入本地及网络驱动器、目录、文件以及它们的大小（按从大到小次序排列），并且您可以对勾选资源批量地进行一些常用操作，例如移动到回收站、彻底删除、移动/复制到其他地方。此外，它也为驱动器/文件/目录提供一些特殊命令（如取得完整路径）。所以，您可以使用一棵树专业版来轻松地进行手动磁盘清理工作。

实际上，它与 UNIX/Linux 的 du 命令类似，或您可以将它视作 Windows 上的具有图形用户界面的 du 工具。

试用版限制：您只能查看前三层资源的大小。

# 查看资源大小

启动后，一棵树专业版将加载所有驱动器以及占用空间最小的驱动器的第一层资源。点击一个资源（驱动器 / 目录）将加载它的第一层资源（文件 / 目录）。
此外，您可以通过映射的网络驱动器来查看远程电脑上的资源大小树（别忘记打开“偏好”界面上的对应开关）。

# 执行操作

在一棵树专业版中，您可以对勾选 / 高亮资源执行以下操作。
图标 命令 适用于 工作模式 上下文菜单 快捷键
删除 彻底删除 勾选资源 批量 右侧列表 <Shift+Del>
回收站 移动到回收站 <Del>

重命名 重命名 高亮资源 单个 左侧树状视图 <F2>
取得完整路径 取得完整路径 <F4>

# 设置偏好

一棵树专业版也为您提供一些自定义界面的选项，如树状视图的字体、工具栏位置及数据分隔符（用于分隔资源的名称和大小）、是否显示光驱及网络驱动器。并且您可以在保存前预览树状视图字体及工具栏位置的效果。

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
