What BackendsideFTP is

BackendsideFTP is a file transfer client for Windows that connects to servers and moves files between them and a computer. It supports FTP, FTPS with explicit or implicit TLS, and SFTP over SSH. Users can open multiple server connections in tabs and authenticate with a password or SSH private key. A shared transfer queue displays progress and speed, with controls to pause, resume, or cancel transfers; it can also retry automatically and enforce a configurable concurrency cap.

The client can browse remote directories and transfer files or folders in either direction. Users can create folders, rename items, and delete files or folders. Site Manager stores connection details for one-click reconnection, while Quick Connect allows a connection without saving a profile. Saved passwords are protected using Windows encryption tied to the user's account. SFTP host keys and FTPS certificates are verified, with options to trust once, trust always, or reject; a changed fingerprint prompts a warning. Additional tools include a visual CHMOD editor, transfer history, app-wide speed limiting, auto-reconnect, keep-alive, and an activity log with verbosity controls. BackendsideFTP is free, with no subscription or ads, and requires 64-bit Windows 10 or 11.
