What BackendsideFTP is
BackendsideFTP is a free Windows file transfer client for connecting to multiple servers and moving files between a computer and remote locations. It supports FTP, FTPS with explicit or implicit TLS, and SFTP over SSH. Connections can use a password or an SSH private key, and separate server sessions can remain open in tabs. A unified transfer queue shows live progress and speed, with controls to pause, resume, cancel, retry automatically, and limit concurrent transfers. Users can browse remote directories, drag files and folders in either direction, create folders, rename items, and delete files or folders. Site Manager stores connection details for one-click reconnection, while Quick Connect avoids saving a profile. Saved passwords use Windows encryption tied to the account. Host keys and certificates can be trusted once, always, or rejected, with changed-fingerprint warnings. Other tools include CHMOD editing, history, speed limits, auto-reconnect, keep-alive, and activity logging. It requires 64-bit Windows 10 or 11.
