Default [Q] Rom Manager back up

Ok so i just did it and bought the premium version of Manager so i can download the back ups to my PC... but i have a problem here

What i download is a Zip file but recovery doesnt find it (or recognize it) when i place it back into my phone, am i supposed to unzip the file or put it in some hidden folder ?

So far was using the backup already on my phone but with 14gb i needed those extra 1.5gb

Thank you beforehand
