FileZilla Overview
FileZilla is a Free (GPL) FTP, FTPS, and SFTP client for Windows, macOS, and Linux maintained by Tim Kosse. The FileZilla offline installer is a self-contained package that can be downloaded once from the official release host and reused for local installs. The FileZilla standalone installer satisfies that requirement directly. FileZilla includes site management, transfer queue controls, bookmarks, directory comparison, speed limits, filename filters, and support for secure file transfers. To install offline: download the matching FileZilla package below, transfer it to USB or a deployment share if needed, and run or extract it on a compatible Windows, macOS, or Linux machine.
