While FTP OutBox is outstanding at both uploading and downloading files, it still lacks some of the more advanced features found in competing FTP clients. FTP OutBox won't allow you to carry out low-maintenance changes to remote files such as creating new directories, changing file names, viewing text files, etc.
Additional features absent in FTP OutBox include an option for selecting a default group of servers to send files to (allowing you to bypass the server selection screen and, as a result, transfer files even more efficiently) and the ability to use the sheduling agent to send only files that are newer than those already on the remote server or servers (for quicker and more efficient synchronization of sites).
