删除文件夹内容，但不删除文件夹 [英] Deleting Folder Contents but not the folder

问题描述

我有一个文件夹C：\Epson Scans，我试图找出如何写一个脚本，将删除文件夹的内容，但保留文件夹完好无损。我已经想出了如何删除整个文件夹，我可以重新创建它。但我想知道是否有人知道一种方法，只是删除文件夹中的内容，而不是实际删除文件夹。任何帮助这将非常感谢！

编辑：插入工作代码，以便我可以循环通过许多计算机，并一次做。有人可以告诉我为什么代码不工作，我已经插入它？

  @echo off 
 setlocal enabledelayedexpansion 
 set Delete_success = 0 
 set total = 0 
 
 for / F %% G in（pclist.txt）do（
 set / a total + = 1 
 
 
 pushdC：\ Epson Scans|| exit / B 1 
 for / D %% I in（*）do（
 rd / S / Q%%〜I
）
 del / Q*
 popd 
 
 if！ERRORLEVEL！== 0（
 set / a Delete_success + = 1 
）else（
 echo EpsonDelete copy failed failed %% G>> EpsonDelete_FailedPCs.txt 
）
 
）
 echo删除成功：％Delete_success％/％total％>> EpsonDelete_FileCopy.txt 
  

解决方案>

del 只删除文件，因此 del / S / QC：\ Epson Scans指定文件夹和子文件夹中的所有文件（由于 / S ）。

rmdir 删除文件夹，因此指定 rmdir / S / QC：\ Epson Scans爱普生扫描本身。

当然，您可以执行 mkdirC：\Epson Scans，然后再次新创建已删除的文件夹 ¹ ，但没有要求。所以正确的答案是使用 for / D 循环 C：\Epson Scans 包含，然后使用 del / Q 删除文件：

  pushdC：\Epson Scans|| exit / B 1 
 for / D %% I in（*）do（
 rd / S / Q%%〜I
）
 del / *
 popd 
  

注意 rd 与 rmdir 相同 - 另请参阅此帖子：什么是MD和MKDIR批处理命令？

_{1）注意，如果你这样做，一些文件夹属性会丢失，此外，这种情况会丢失，因为Windows不区分大小写处理路径。}

I have a folder C:\Epson Scans, I am trying to figure out how to write a script that will delete the contents of the folder but leave the folder intact. I have figured out how to delete the entire folder and I could recreate it. But I wanted to know if anyone knows a way of just deleting the contents inside the folder and not actually deleting the folder. Any help with this would be greatly appreciated!

Edit: Inserting working code so I can loop through many computers and do it at once. Will someone please tell me why the code is not working where I have inserted it?

@echo off
setlocal enabledelayedexpansion
set Delete_success=0
set total=0

for /F %%G in (pclist.txt) do ( 
    set /a total+=1


pushd "C:\Epson Scans" || exit /B 1
for /D %%I in ("*") do (
    rd /S /Q "%%~I"
)
del /Q "*"
popd

if !ERRORLEVEL!==0 (
        set /a Delete_success+=1
    ) else (
        echo EpsonDelete copy failed on %%G>>EpsonDelete_FailedPCs.txt
    )

)
echo Delete Success: %Delete_success%/%total% >>EpsonDelete_FileCopy.txt

解决方案

del deletes files only, so del /S /Q "C:\Epson Scans" deletes all files in the given folder and sub-folders (due to /S).

rmdir deletes folders, so specifying rmdir /S /Q "C:\Epson Scans" also deletes the folder Epson Scans itself.

Of course you could execute mkdir "C:\Epson Scans" afterwards to newly create the deleted folder again¹, but this was not asked for. So the correct answer is to use a for /D loop over C:\Epson Scans and delete each folder it contains, and then use del /Q to delete the files:

pushd "C:\Epson Scans" || exit /B 1
for /D %%I in ("*") do (
    rd /S /Q "%%~I"
)
del /Q "*"
popd

Note that rd is the same as rmdir -- see also this post: What is the difference between MD and MKDIR batch command?

_{1) Regard that some folder attributes get lost if you do that, for example the owner. Also the case is lost as Windows treats paths case-insensitively.}
