Need assistance with Obb folder on Zarchiver

Okay so im attempting to Obtain a video-game that I wanna play and I have to Hack it. However to be able to try this i first should rename it within the Obb folder of Android on Zarchiver. I needed to uninstall Zarchiver a while in the past to clear the house of my cellphone and all the things labored simply fantastic again then. Now I needed to set up it again to Hack that Sport however after I tried to go On the Obb folder it retains saying that message, that the entry is denied and the Obb folder is empty. As you possibly can see within the video I first went to yellow app referred to as "my recordsdata" and as I checked the Obb folder, it was empty. Then I went to the blue App "Recordsdata" and there, the Obb folder was full. However as I attempted to apply it to Zarchiver it retains telling the Obb folder is empty. Can any individual inform me what's improper with it and presumably if there’s a approach to restore it. I’m going Loopy!!!! I’ve a Samsung Galaxy A12.
