Excellent file manager, even more functional, than my personal favorite FX manager.
+ advanced file management
+ zip/rar archive support
+ access your home PC via WiFi with SMB
+ FTP and WebDAV client
+ FTP server: convenient access to phone/tablet's files via FTP protocol
+ supports Dropbox, Box.net, Sugarsync, Google Drive
- not so nice, in terms of graphics and overall looks
