Hi there,  
I’m trying to dump HAR file using mitmdump on Win 10. I am using the example har\_dump.

```
mitmdump -s examples/complex/har_dump.py -w dump.mitm --set hardump=dump.har

```

I launch this command in cmd/powershell and everything is okay, I can see the flow in real-time.  
The problem is that when I stop the command (CTRL+C), I obtain only the dump.mitm file. Where is the har file?

Thanks for help.

This is just a guess, but what happens if you leave off the `-w dump.mitm` option?

Also, see [How to export projects to format for non mitmproxy users to view?](https://discourse.mitmproxy.org/t/how-to-export-projects-to-format-for-non-mitmproxy-users-to-view/966/4) for how to take your `dump.mitm` file and convert it to HAR.

Same result for me…
