如何使用保留名稱刪除此類文件？

Question

嗨，給大家在stackoverflow！

我正在尋找的解決方法，如何使用保留的名稱，刪除這種文件：

(nul, aux, com1, prn, etc...)

所以，我得到的輸出誤差：

的語法文件名稱，目錄或卷不正確。

@echo off 
echo hello world>\\?\"%temp%\nul:nul" 
pause 
more<"%temp%\nul:nul" 
pause 
set /p MyVar=<"\\?\%temp%\nul:nul" 
echo %MyVar% 
Pause 
Del "\\?\%temp%\nul:nul" /F 
pause 

我用這種伎倆來存儲下面 所以在這個代碼所示像密碼，我可以設置密碼進入這個文件也，從它讀，但我不能刪除它。

@echo off

這爲我工作：

del "\\.\%temp%\nul" 

由於微軟說，在 https://support.microsoft.com/en-us/kb/120716， 你需要使用它繞過了保留名稱檢查語法。
