Open a Zip file with another extension

Hello

I need to unzip files that are zip files, but have different extension.

For example, a file like this Sample.cpn is a Zip File, I just don’t want customers to know that it is a zip file, that is why I change the extension programmatically within VB.Net.

So when I am working with Opus I want to double-click on the file and that Opus shows me which files are within the zip file.

I don’t want to extract the files, just to see the files.

I did this already with another extension and it is working with extension .nmb, but that was with version 9 and I can’t remember how I did it.

Can someone help me?

In Preferences, do you not just add the extension to the following box?

Settings - Zip & Other Archives - Zip Files

Zip Extensions .zip;.jar;.exe etc
