If you are looking for a really elaborate FTP client, you should take SmartFTP into account. If all FTP connection programs are normally identical, SmartFTP has decided not to follow the general rule of this kind of application and includes all the features that it should, within an interface that has been thoroughly designed and optimized.
A practical, fast, and safe FTP client
SmartFTP has support for FTP and FTPS over SSH, for secure connections, and as well as the modern interface, it includes folder synchronization, more than 20 different languages available, that install once it is started for the first time, preview images as thumbnails, IPv6, Mode Z on-the-fly compression, and it makes sure the transfers have taken place correctly by means of XCRC, XMD5, and XSHA.
With SmartFTP, we will also be able to search and edit files on the remote server, and use multiple connections, amongst many other features that make this FTP client one of the most complete on the market.
