Fastest way to delete a tree of directories in batch file
提问by Assaf Lavie
I need to write a batch file that received a directory that contains a huge number of empty sub-directories and deletes them all.
我需要编写一个批处理文件，该文件接收一个包含大量空子目录的目录并将它们全部删除。
What's the fastest way of doing this? (by fast I mean not like what Windows Explorer does when you try to delete such a directory...)
这样做的最快方法是什么？（快速我的意思是不像 Windows 资源管理器在您尝试删除这样的目录时所做的那样......）
Clarification:
澄清：
I'm not trying to delete onlyempty directories. It just so happens that this dir I'm trying to delete is mostly empty sub-dirs.
我不是想只删除空目录。碰巧的是，我要删除的这个目录大多是空的子目录。

rd yourdirname /s/q
Will do the job regardless of whether they are empty or not.
无论它们是否为空，都将完成工作。

I'm not sure if I understood the question. If you just want to delete the tree then you can just use rd /s. However, if you only want to delete emptydirectories, then you can do the following using Cygwin.
我不确定我是否理解这个问题。如果您只想删除树，那么您可以使用rd /s. 但是，如果您只想删除空目录，则可以使用 Cygwin 执行以下操作。
find -type d -empty | xargs rmdir
The standard IT build where I work has Cygwin installed, and I've used this more than once.
我工作的标准 IT 版本安装了 Cygwin，我已经不止一次使用过它。
