I've downloaded a world from the internet and now want to play it in Minecraft PE on Android. I've found tutorials online but they say I have to extract the world folder into a folder named "games" which I do not seem to have.
After you download the app simply go into "settings" in the app you can enable "show hidden files" which will let you see the "games" folder and everything inside it. Perhaps try downloading a different file manager app if you can't unhide your files. I use the File Manager app so whatever app you use might not have the exact same procedure, though you can download and install worlds from from the app I use.
