Redirect the output of the delcommand to nul. Note the 2, to indicate error output should be redirected. See also this question, and especially the tech doc Using command redirection operators.
将del命令的输出重定向到 nul。请注意2, 以指示应重定向错误输出。另请参阅此问题，尤其是使用命令重定向操作符的技术文档。
del {whateveroptions} 2>nul
Or you can check for file existence before calling del:
或者您可以在调用之前检查文件是否存在del：
if exist c:\folder\file del c:\folder\file
Note that you can use if exist c:\folder\(with the trailing \) to check if c:\folderis indeed a folder and not a file.
请注意，您可以使用if exist c:\folder\（带有尾随\）来检查是否c:\folder确实是文件夹而不是文件。

Either redirect stderr to nul
要么将 stderr 重定向到 nul
rd /q /s "c:\yourFolder" 2>nul
Or verify that folder exists before deleting. Note that the trailing \is critical in the IF condition.
或者在删除之前验证该文件夹是否存在。请注意，尾随\在 IF 条件下至关重要。
if exist "c:\yourFolder\" rd /q /s "c:\yourFolder"

For me on Windows 10 the following is working great:
对我来说，在 Windows 10 上，以下工作很好：
if exist <path> rmdir <path> /q /s
qstands for "delete without asking" and sstands for "delete all subfolders and files in it".
q代表“不问就删除”，s代表“删除其中的所有子文件夹和文件”。
And you can also concatinate the command:
您还可以连接命令：
(if exist <path> rmdir <path> /q /s) && <some other command that executes after deleting>

The above comes up with Y or N in the prompt. So, I used the following instead and it works perfectly.
以上在提示中出现了 Y 或 N。所以，我改用了以下内容，并且效果很好。
if exist cddd rmdir cddd
Hope this helps someone.
