How to delete all files and folders in a folder by cmd call
提问by ufukgun
I use Windows.
我使用 Windows。
I want to delete all files and folders in a folder by system call.
我想通过系统调用删除文件夹中的所有文件和文件夹。
I may call like that:
我可以这样称呼：
>rd /s /q c:\destination
>md c:\destination
Do you know an easier way?
你知道更简单的方法吗？

No, I don't know one.
不，我一个都不认识。
If you want to retain the original directory for some reason (ACLs, &c.), and instead really want to empty it, then you can do the following:
如果您出于某种原因（ACL，&c.）想保留原始目录，而实际上想清空它，那么您可以执行以下操作：
del /q destination\*
for /d %x in (destination\*) do @rd /s /q "%x"
This first removes all files from the directory, and then recursively removes all nested directories, but overall keeping the top-level directory as it is (except for its contents).
这首先从目录中删除所有文件，然后递归删除所有嵌套目录，但总体上保持顶级目录不变（除了其内容）。
Note that within a batch file you need to double the %within the forloop:
请注意，在批处理文件中，您需要%在for循环内加倍：
del /q destination\*
for /d %%x in (destination\*) do @rd /s /q "%%x"
回答by Sean
del c:\destination\*.* /s /qworked for me. I hope that works for you as well.
del c:\destination\*.* /s /q对我来说有效。我希望这也适用于你。

I think the easiest way to do it is:
我认为最简单的方法是：
rmdir /s /q "C:\FolderToNotToDelete\"
The last "\" in the path is the important part.
路径中的最后一个“\”是重要的部分。

Yes! Use Powershell:
是的！使用 Powershell：
powershell -Command "Remove-Item 'c:\destination\*' -Recurse -Force"

If the subfolder names may contain spaces you need to surround them in escaped quotes. The following example shows this for commands used in a batch file.
如果子文件夹名称可能包含空格，您需要用转义引号将它们括起来。以下示例为批处理文件中使用的命令显示了这一点。
set targetdir=c:\example
del /q %targetdir%\*
for /d %%x in (%targetdir%\*) do @rd /s /q ^"%%x^"

To delete file:
删除文件：
del PATH_TO_FILE
To delete folder with all files in it:
要删除包含所有文件的文件夹：
rmdir /s /q PATH_TO_FOLDER
To delete all files from specific folder (not deleting folder itself) is a little bit complicated. del /s *.*cannot delete folders, but removes files from all subfolder. So two commands are needed:
从特定文件夹中删除所有文件（不删除文件夹本身）有点复杂。del /s *.*不能删除文件夹，但会从所有子文件夹中删除文件。所以需要两个命令：
del /q PATH_TO_FOLDER\*.*
for /d %i in (PATH_TO_FOLDER\*.*) do @rmdir /s /q "%i"
You can create a script to delete whatever you want (folder or file) like this mydel.bat:
您可以创建一个脚本来删除您想要的任何内容（文件夹或文件），如下所示mydel.bat：
@echo off
setlocal enableextensions
if "%~1"=="" (
echo Usage: %0 path
exit /b 1
)
:: check whether it is folder or file
set ISDIR=0
set ATTR=%~a1
set DIRATTR=%ATTR:~0,1%
if /i "%DIRATTR%"=="d" set ISDIR=1
:: Delete folder or file
if %ISDIR%==1 (rmdir /s /q "%~1") else (del "%~1")
exit /b %ERRORLEVEL%
Few example of usage:
几个用法示例：
mydel.bat "path\to\folder with spaces"
mydel.bat path\to\file_or_folder

One easy one-line option is to create an empty directory somewhere on your file system, and then use ROBOCOPY(http://technet.microsoft.com/en-us/library/cc733145.aspx) with the /MIRswitch to remove all files and subfolders. By default, robocopy does not copy security, so the ACLs in your root folder should remain intact.
一个简单的单行选项是在文件系统的某处创建一个空目录，然后使用ROBOCOPY( http://technet.microsoft.com/en-us/library/cc733145.aspx) 和/MIR开关删除所有文件和子文件夹。默认情况下，robocopy 不复制安全性，因此根文件夹中的 ACL 应保持不变。
Also probably want to set a value for the retry switch, /r, because the default number of retries is 1 million.
也可能想为重试开关设置一个值/r，因为默认的重试次数是 100 万次。
robocopy "C:\DoNotDelete_UsedByScripts\EmptyFolder" "c:\temp\MyDirectoryToEmpty" /MIR /r:3

I had an index folder with 33 folders that needed all the files and subfolders removed in them. I opened a command line in the index folder and then used these commands:
我有一个包含 33 个文件夹的索引文件夹，需要删除其中的所有文件和子文件夹。我在 index 文件夹中打开了一个命令行，然后使用了这些命令：
for /d in (*) do rd /s /q "%a" & (
md "%a")
I separated them into two lines (hit enter after first line, and when asked for more add second line) because if entered on a single line this may not work. This command will erase each directory and then create a new one which is empty, thus removing all files and subflolders in the original directory.
我将它们分成两行（在第一行之后按 Enter，当要求更多时添加第二行），因为如果在一行上输入，这可能不起作用。此命令将擦除每个目录，然后创建一个新的空目录，从而删除原始目录中的所有文件和子文件夹。

It takes 2 simple steps. [/q means quiet, /f means forced, /s means subdir]
只需 2 个简单的步骤。[/q 表示安静，/f 表示强制，/s 表示子目录]
Empty out the directory to remove
del *.* /f/s/qRemove the directory
cd .. rmdir dir_name /q/s
清空要删除的目录
del *.* /f/s/q删除目录
cd .. rmdir dir_name /q/s
