The main features of FileZilla are:
Ability to resume Uploads/Downloads (if the server supports it)
Site Manager with folders
Keep Alive system
SOCKS4/5 and HTTP1.1 Proxy support
SSL secured connections
GSS authentication and encryption using Kerberos
filezilla ftp sftp ssl ftp client kerberos open source
1License and operating system information is based on latest version of the software.
Caveat: No FXP support (yet).
Additionally, the directory caching would be much appreciated. Overall, Filezilla is a great tool, specially if you need a SFTP client, but sometimes its responsiveness is somewhat slow.
