Appears to be abandoned Last update was in March 2015. It crashes too much and its FTP implementation (SFTP in particular) is extremely buggy. A shame because this application appears to be a promising alternative to adware (ES File Explorer)  and an alternative to another closed off file manager  which locks key features  such as FTP  behind a paywall (Fx File Explorer. Seriously? Even Windows does that out of box).
