Hi, you can’t directly interact with local file from browser, it’s blocked because of security reasons. But there is a way to workaround this problem. You can use “Katalon Helper Tool”. You can read about and download it from:  
[https://docs.katalon.com/katalon-recorder/docs/katalon-recorder-helper-tool.html#introduction](https://docs.katalon.com/katalon-recorder/docs/katalon-recorder-helper-tool.html#introduction)  
It’s small server that listens on 18910 port and execute OS command.

So when you want to delete line from file you just use command open with target set to:

> [http://localhost:18910/execute?cmd=](http://localhost:18910/execute?cmd=)  
> and after “=” sign you can use “powershell deletingFirstLineScript.ps1”  
> and obviously you need to create powershell script named “deletingFirstLineScript.ps1” which will delete this line.
