Changelog

Full release history and version notes for BackendsideFTP – FTP, FTPS & SFTP Client for Windows.

Version 3.0.1

Latest June 2026

A 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

Version 1.0

January 2026

Initial Release

  • Multiple simultaneous FTP connections — each in its own independent MDI child window
  • Built-in local file explorer with Desktop, My Computer, and all drive letters
  • Threaded uploads with real-time KB/s speed reporting and abort option
  • Threaded downloads with live progress tracking and overwrite dialog
  • Saved site manager — hostname, port, credentials, default directory, Active/Passive mode
  • Quick Connect for instant sessions without saving a full site profile
  • Remote file and folder management — create, rename, delete, refresh via context menu
  • File permissions editor (CHMOD) with visual read/write/execute checkboxes
  • Toggle visibility of hidden dot-files on Unix servers
  • Encrypted credential storage using the Windows CryptoAPI — no plain-text passwords on disk
  • Color-coded activity log per connection window — blue for server replies, red for errors
  • Sortable remote file list by name, size, owner, group, or date modified
  • Supports Windows 7, 8, 10, and 11 (32-bit and 64-bit)
