Yes it is missing perhaps some features that you may get in other ftp programs but since it is free and feature rich it is more than likely to fit the needs of the majority of users While using the server side of things you can use Cyberduck as a file manager as it allows creating duplicate copies of files, creating new folders, deleting files and a simple way to set up permissions to files which is very important on many web-sites to help control access and security. You can also store bookmarks of the configurations you set up to connect to file servers thus making subsequent connections to the same server only a click away. The preferences allow you to resume large downloads by setting things like skipping files that match etc, which is very good for my voluntary work updating a whole website. It allows you to upload and download files using a variety of standard ftp protocols. The cost is free and they suggest a donation which is very noble of them for such a great product. IT is a unique product for being free and I encourage any user to support them with a small donation as to keep the evolution of this product going.

Comments: I have used Cyberduck primarily for looking after a hobby flight simulation website, but also in a role as a freelance software developer I have used the product to upload my work to client servers without any problems with permissions or client requirements.
