windows - 如何删除 Windows 上以点 (.) 结尾的目录？

Question

我错误地创建了一个文件，而且我这辈子都无法删除它。如果你有 7-Zip安装好了，就可以生产了。如果没有，很容易安装。

文件的创建方式如下:

PS C:\temp> mkdir abc
PS C:\temp> cd abc

PS C:\temp\abc> & 'C:\Program Files\7-Zip\7z.exe' a -spf .\DuoWindowsLogon.admx,.\en-us\DuoWindowsLogon.adml

Creating archive: .\DuoWindowsLogon.admx,.\en-us\DuoWindowsLogon.adml

后来，我了解到我应该输入的正确命令是:

& 'C:\Program Files\7-Zip\7z.exe' a abc.7z -spf DuoWindowsLogon.admx en-us\DuoWindowsLogon.adml

意识到错误后，我尝试删除错误创建的目录:

PS C:\temp\abc> ls
d-----       11/15/2020  11:09 PM                DuoWindowsLogon.admx,.

PS C:\temp\abc> ls D*
ls : Could not find item C:\temp\abc\DuoWindowsLogon.admx,..

PS C:\temp\abc> ls | rm
rm : Cannot find path 'C:\temp\abc\DuoWindowsLogon.admx,.' because it does not exist.

PS C:\temp\abc> rm *
rm : An object at the specified path C:\temp\abc\DuoWindowsLogon.admx,. does not exist.

PS C:\temp\abc> cd ..
PS C:\temp> rm -recurse abc
rm : Could not find a part of the path 'C:\temp\abc\DuoWindowsLogon.admx,'.

如您所见，没有任何效果。我还尝试了文件资源管理器 (GUI)，它也不起作用。如何删除目录？

附言:

我在 CMD 提示符下尝试了“del/s”，它没有产生错误，但文件没有被删除:

c:\>del /s c:\temp\abc
c:\temp\abc\*, Are you sure (Y/N)? Y

c:\>dir c:\temp\abc
11/15/2020  11:09 PM    <DIR>          DuoWindowsLogon.admx,.

Answer 1

您可以删除以“.”结尾的目录。通过在其前面加上 \\?\

前缀

因此，在您的情况下，您可以使用:

Remove-Item `\\?\C:\temp\abc\DuoWindowsLogon.admx,.` -Recurse

此处记录:You can't delete a file or a folder on an NTFS file system volume

You may not be able to delete a file if the file name includes aninvalid name (for example, the file name has a trailing space or atrailing period or the file name is made up of a space only). Toresolve this issue, use a tool that uses the appropriate internalsyntax to delete the file. You can use the "\\?\" syntax with sometools to operate on these files, for example:

del "\\?\c:\<path_to_file_that contains a trailing space.txt>"

The cause of this issue is similar to Cause 4. However, if you usetypical Win32 syntax to open a file that has trailing spaces ortrailing periods in its name, the trailing spaces or periods arestripped before the actual file is opened.
