How to import a Test Suite?

I have created 3 Macros under a folder. Followed by exported the whole folder with all the Marcos using “Create a Backup” option. This creates a zip file.

Now I want to open this zip file in another system and Import the whole test suite. How do I do that?
When i try to click “Import JSON or ZIP” and point to the Zipped folder it throws error “[error]
in parsing This is a test suite, not a macro”

Switch to hard drive mode and you can copy fiels inside folders and run test suite

Thank you. That helps
