Frequently Asked Questions

Is FileZilla Server secure for internet use?

Yes, when properly configured with FTPS (FTP over SSL/TLS), FileZilla Server provides secure encrypted file transfers. However, you must generate or install SSL certificates, use strong passwords, configure IP filtering, and keep the software updated. For maximum security, consider using SFTP servers instead, though FileZilla Server doesn’t support SFTP.

What’s the difference between FileZilla Client and FileZilla Server?

FileZilla Client is FTP client software that connects to FTP servers to upload/download files (like a web browser for FTP). FileZilla Server is FTP server software that hosts files and allows others to connect to your computer to transfer files. Most users need only the Client; Server is for those hosting their own FTP service.

Can I use FileZilla Server for commercial purposes?

Yes, FileZilla Server is licensed under GNU General Public License (GPL), allowing free use for both personal and commercial purposes without licensing fees. You can use it in business environments, charge for services that utilize it, and install unlimited instances.

How many users can connect simultaneously?

FileZilla Server has no hard-coded user limits. The number of simultaneous connections depends on your server’s hardware resources (CPU, RAM, network bandwidth) and your configured connection limits. Typical home servers handle 10-50 concurrent users; properly configured dedicated servers can support hundreds of connections.

Final Verdict

FileZilla Server stands as an excellent free FTP server solution for Windows users who need reliable file sharing capabilities without licensing costs. Its combination of user-friendly administration, robust security features through FTPS support, and unlimited user capacity makes it ideal for small businesses, developers, and home users seeking professional-grade FTP hosting.

While lacking SFTP support and cross-platform availability, FileZilla Server delivers solid performance and comprehensive features that meet most FTP server needs. The active development community ensures regular updates and security patches, maintaining its position as a trusted solution. Download FileZilla Server from filezilla-project.org and create your own secure file transfer infrastructure without the expense of commercial alternatives.
