Remember the legacy File Manager from the Android Open-source Project? In modern versions of Android, the default file manager is Google Files. However, the legacy File Manager app is still hidden within the system! Using Tweak It's launcher, users who prefer the legacy File Manager can open it easily!
If you would like to give it a try, version 1.3 of Tweak It is available on the Google Play Store!
