FileZilla Server is one of the best FTP servers currently on the market, offering a wide array of features, all available in a free package.

The program is undoubtedly a top product, so the user has to pay attention to every single step included in the installer.

Besides the fact that he has to select the components he wishes to install, the user can pick from up to three options regarding the way the FileZilla Server should be started: as a service with Windows, manually or automatically.

The main window of the program is actually the one where the log file is displayed, thus letting you know exactly what's happening with the service, regardless if we're talking about connections, transfers or other actions.

But the most important part is the configuration. There are three main sections offering customization options, “Setup”, “Users” and “Groups”, each with its very own pack of settings.

In “Settings” you can change basically everything about the server, including IP bindings, IP filter, passive mode security, security tools, logging, admin interface, speed limits, autoban, SSL and TLS settings and file transfer compression.

The “Users” and “Groups” sections are obviously reserved to accounts settings, with dedicated tools concerning shared folders, speed limits and IP filters.

FileZilla Server doesn't eat up too much of your CPU and RAM, and it sits quietly in the System Tray, but minor slowdowns may occur when the connected clients download files at high speeds.

But all in all, there is no doubt that FileZilla Server is a top product. And what's more, it's free.
