When you open the app for the first time, tap Allow to give the app permission to run. You’ll then be redirected to your Settings, where you need to tap the switch next to “Allow access to all files. " Tap the back arrow in the top left corner to return to the app. If your Android is a Samsung Galaxy model, you can also use the My Files app to open and unzip files.
When you tap to select the ZIP file, you’ll see a pop-up window that shows you all the files and folders inside the compressed ZIP file.
To delete the . zip folder after you’ve extracted everything, tap to check the “Delete ZIP file” box.
