Tandem Commander Pavel Stupka

Tandem Commander is an open-source two-panel (dual-pane) file manager for Windows. It is a native application - there is no runtime to install and it starts instantly. Both panels show a directory, and every operation - copy, move, delete, rename, pack, unpack, compare - works between them and can be driven entirely from the keyboard. Common archive formats are browsed like ordinary folders. A plugin architecture adds file viewers, FTP and SFTP clients, checksum tools, a Markdown viewer and more. It offers full Unicode and long-path support, a dark theme, sync-status badges for cloud-synced folders, and a configurable command shell. Tandem Commander is built with AI-assisted, spec-driven development under human direction and review, and is provided "as is", without warranty of any kind.
