Date: 2017feb14 OS: Android Q. Which Android file manager do you use? A. I use Amaze. - Open Source - Does whats needed - Material Design - FTP server included - Can connect to SMB (Windows network) https://play.google.com/store/apps/details?id=com.amaze.filemanager (I used to ES File Manager but it put ads in the sleep screen and generally jumped the shark.)
