Tap the zip file. This will create a new folder with the contents of the zip file.
Tap the folder to open it.

On the “Files” app, tap “Browse”. Then select the folder that contains the zip file.
Tap the zip file. It will open a pop-up, showing what is inside the file.
Tap “Extract”. If you want to delete the zip file after unzipping it, check the "Delete zip file" box.
Tap “Done”. The contents of the zip file are now extracted to the current folder.
