&nbsp;Hi!

We run fb 6.1. We have 7-zip installed.

We create a 7z archive with a password. That works fine. But the file names inside the 7z are not encrypted. &nbsp;How do we do that?

Thanks!!

Hi Sam,   
  
 The action doesn’t have an option which exposes the encrypt headers command line argument, you’ll need to add ‘-mhe’ to the ‘Extra params at end’ action property.

Ummmm, in 6.1, where is the "Extra params at end" action property?

Hi Sam,   
  
 Select action -\> View -\> Action Properties Tab (F4) -\> Extra Command Line Parameters -\> Extra Params at End
