Version 3.0.1
Latest June 2026A complete, ground-up redesign. BackendsideFTP is now a multi-protocol client with a clean, modern interface, light and dark themes, and a unified transfer queue — adding FTPS and SFTP alongside plain FTP.
New — Protocols & Security
- Added FTPS (explicit and implicit TLS encryption) and SFTP over SSH alongside plain FTP
- Authenticate with a password or an SSH private key
- SSH host-key trust store and TLS certificate trust, with Trust once / Trust always / Reject prompts and a warning if a fingerprint ever changes
- Plain-English error messages when a connection fails
- Keep-alive pings so idle sessions aren't dropped by the server's timeout
- Auto-reconnect with exponential backoff that restores the folder you were browsing
New — Sessions & Transfers
- Tabbed multi-sessions — open many servers at once, each tab an independent connection with its own worker
- Unified transfer queue shown as a tree: folders with nested child files, live progress bars, real-time speed, and rolled-up parent totals
- Pause, resume, cancel and retry any transfer; resume picks up where a paused transfer left off
- Automatic retry with backoff, a configurable concurrency cap, and a per-transfer idle timeout
- App-wide speed limit to cap bandwidth, and a persisted transfer history across launches
- Per-transfer overwrite policy — Overwrite, Skip, Rename or Fail
New — Browsing & Files
- Drag-and-drop in both directions, with multi-select and recursive whole-folder transfers
- Right-click context menus in both the local and remote panes
- Native Windows file and folder icons in both panes
- Quick-locations dropdown (Desktop, Documents, Downloads, drives) in the local pane
- Loading indicator while remote folders load, and a confirmation prompt before deleting remote files or folders
- Quick Connect port auto-fills from the chosen protocol
New — Interface & Convenience
- Modern redesigned interface with light and dark themes, toggled in one click and remembered between launches
- Window size, position and pane layout restored on relaunch
- Global Settings window — speed limit, default connection mode, keep-alive, and log verbosity
- Activity log with adjustable verbosity, up to a full protocol transcript, plus an "open log folder" shortcut
- System tray with minimize-to-tray and double-click restore
- Keyboard shortcuts for new session, Site Manager, upload, and closing the active tab
- New splash screen, redesigned About dialog, and a friendly crash recovery dialog
