The Archive feature on Android 15 and later allows users to remove an app and its associated files from their device while retaining customization. To use it, go to Settings, find the Apps section, select the desired app, and choose the Archive option. The app will be removed from storage but remain visible in the apps list. To restore it, tap on the app and select Restore, which reinstalls it with all previous settings, though updates and maintenance tasks will still be necessary.
