删除文件夹中的子目录但保留单个文件

Question

我正在尝试创建自己的批处理文件来删除文件夹的子目录，但保留文件和顶层。我知道我可以这样做，RMDIR <folderName> /S /Q但如果可以避免的话，我真的不想对每个文件夹都这样做。

有没有一种简单的方法可以删除目录中的所有文件夹但保留顶层文件？谢谢

Answer 1

执行此操作的命令是：

FORFILES /C "cmd /c if @isdir==TRUE echo rmdir @file /s /q"

如果输出看起来正确，删除单词 echo。命令变为：

FORFILES /C "cmd /c if @isdir==TRUE rmdir @file /s /q"

请注意，第二条命令是不可逆的。如果输入错误，您将丢失数据。因此，在继续执行第二条命令之前，请仔细检查第一条命令。如有疑问，请进行备份。

Answer 2

for /d %i in (*)do rmdir /q /s .\"%~i"\.

避免使用forfileswith cmd /c，请遵循ss64.com建议，改用for /D循环：

• For /D有条件地对多个命令执行目录/文件夹。

• Bugs
  
      Recent versions of FORFILES contain a bug, in processing command line arguments:
      running a /c command that contains an argument such as FORFILES /C "PING -a" will fail.
      The expected convention is that argv[0] will contain the program name, but FORFILES
      instead passes the first argument as argv[0]. Old versions e.g. FORFILES version 1.46
      (24th March 2006) do not suffer from this bug.
      
      One workaround for this is to include the program name as the first argument,
      this will be passed along by FORFILES and the CreateProcess call will then work
      as expected:
      FORFILES /c "Ping Ping -a".
      
      Alternatively pass the command to CMD /C, which will then process all the arguments
      correctly. If you want to use an internal commmand, or if you want to use redirection,
      pipe, command concatenation, etc, then you must use CMD /C.
      FORFILES /c "CMD /C Ping -a"
      
      There are some disadvantages to using CMD.exe with FORFILES, a new process will be
      created and destroyed for every file that FORFILES processes, so if you loop through
      1000 files, then 1000 copies of CMD.exe will be opened and closed, this will affect
      performance. Also any variable created with SET will be lost as soon as FORFILES moves
      on to the next file.
      
  
      In most cases using a simple FOR command along with Parameter extensions will provide
      a better/less buggy solution.
