Open a command prompt and use these commands to first rename and then delete the NUL file:

<pre><code>C:\&gt; rename \\.\C:\..\NUL. deletefile.txt
C:\&gt; del deletefile.txt
</code></pre>

Using the <code>\\.\</code> prefix tells the high-level file I/O functions to pass the filename unparsed to the device driver - this way you can access otherwise invalid names.

I had a similar issue. It was probably caused by Cygwin as well (since I use this regularly), but I've since forgotten exactly how the file was created.

I also had trouble deleting it. I followed the advice of some other posts and tried booting into safe mode to delete the file, though this did nothing. The tip from +xxbbcc didn't work for me either.

However, I was able to delete the file using the Cygwin terminal! Cygwin createth and Cygwin destroyeth.

blocks|key|4182340|text|我用一种稍微不同的方式解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4182341|我想我应该在这里添加这个，因为它在google结果中很高，而且我对一个名为NUL的文件夹也有类似的问题。|4182342|我尝试了rmdir\\?\C:\My\Path\NUL和rmdir\\.\C:\My\Path\NUL，但没有成功，我还尝试了几个使用bash的命令，这些命令来自我的SourceTree安装。不是joy。|offset|length|style|CODE|4182343|最后，我使用了cmd中的DIR+/X+/A来列出父目录中的短名称。这向我展示了NUL文件夹的NUL~1，并指出了问题的症结所在。|4182344|然后在标准命令rmdir+/s+NUL~1中使用它，并最终解决了这个问题。|4182345|entityMap^0|0|0|4|N|S|N|0|C|9|1A|5|0|7|E|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@$F|S|G|T|H|I]|$F|U|G|V|H|I]]|9|@]|A|$]]|$1|J|3|K|5|6|7|W|8|@$F|X|G|Y|H|I]|$F|Z|G|10|H|I]]|9|@]|A|$]]|$1|L|3|M|5|6|7|11|8|@$F|12|G|13|H|I]]|9|@]|A|$]]|$1|N|3|-4|5|6|7|14|8|@]|9|@]|A|$]]]|O|$]]

I solved this in a slightly different way. 

I thought I would add this here because it is high in the google results and I had a similar issue for a folder named NUL. 

I tried <code>rmdir\\?\C:\My\Path\NUL</code> and <code>rmdir\\.\C:\My\Path\NUL</code> without any success and also tried several commands using bash from my SourceTree installation. No joy.

In the end I used <code>DIR /X /A</code> from cmd to list the short names in the parent directory. This showed me <code>NUL~1</code> for my NUL folder and identified the crux of the problem.

This was then used in the standard command <code>rmdir /s NUL~1</code> and finally resolved the issue.

If you have Git for Windows Installed (v2.18) do the following 

<ol>
<li>Open the directory containing the files you want to remove</li>
<li>Left Click and select <code>Git Bash Here</code></li>
<li>Type <code>rm nul.json</code> at the command prompt and hit ENTER, the file now should be removed.</li>
</ol>

If you have git on windows, just right click on the folder containing the nul file -&gt; go to gitbash here -&gt; and type &quot;rm nul&quot; or &quot;rm nul.json&quot; depending upon the file type.

I was having this same issue. 
If you have WSL2 installed just go to that directory and run:
<pre><code>rm -f nul

In my case the file was lowercase. You should be good.

I ran a program on Windows 7 that was compiled under Cygwin and passed "NUL" as an output file name. Instead of suppressing output it actually created a file named "NUL" in the current directory. (Apparently it expects "/dev/null", even on Windows.) Now I'm stuck with this "NUL" file that I cannot delete!

I've already tried:

<ul>
<li>Windows Explorer - error: "Invalid MS-DOS function" (yes, that is seriously what it says!)</li>
<li>Command prompt using "del NUL" - error: "The filename, directory name, or volume
label syntax is incorrect."</li>
<li>Deleting the entire directory - same deal as just deleting the file</li>
<li><code>remove()</code> in a C program - also fails</li>
</ul>

How can I get rid of these NUL files (I have several by now), short of installing the full Cygwin environment and compiling a C program under Cygwin to do it?

我在Windows 7上运行了一个程序，该程序在Cygwin下编译，并将"NUL“作为输出文件名传递。它没有抑制输出，而是在当前目录中创建了一个名为"NUL“的文件。(显然它期望"/dev/null"，即使在Windows上也是如此。)现在我被这个我不能删除的"NUL“文件困住了！我已经试过了Windows资源管理器-...
