FileZilla is a cross-platform FTP (File Transfer Protocol), FTPS (FTP over SSL/TLS), and SFTP (SSH File Transfer Protocol) client.

The specific version number 3.59.0 (often searched as "3590" due to shorthand) represents a stable release from the FileZilla project. At the time of its release, this version introduced critical bug fixes, improved security patches, and enhanced compatibility with modern servers.
