An FTP client is a program which installs on your computer and can connect to a web server in order to upload and download files. Because the interface is on your local machine it is very responsive. You can upload very large numbers of files quickly.

While there are a few paid FTP programs, most users will be more than satisfied with the free FTP clients available. And FileZilla is the best option they can have.

FileZilla is the most popular free FTP client currently available. Despite what the name may suggest, it is of no relation to any Mozilla project. However, its popularity is quite similar – it wouldn’t be a stretch to say that Filezilla is the Firefox of free FTP clients.

The reason for FileZilla’s success is functionality. FileZilla may be a free client, but it can do just about anything that you’d need. These features aren’t just arcane or complex functions only web gurus will appreciate, either. One feature which everyone can fall in love with is the ability to drag and drop files to your desktop from FileZilla, and vice versa. The other free FTP clients don’t support this.

FileZilla is compatible with Mac OS X, Linux and Windows.
