Extract text from DUCK files
To convert your DUCK file to another format, you need Cyberduck or other Settings software.
To convert other file formats to the "FTP Connection Profile" file type, you need software like Cyberduck or a similar tool.
A .DUCK file is a server connection bookmark created by Cyberduck, a popular open-source cloud storage browser for macOS and Windows. These files function as shortcuts, storing critical connection parameters such as the FTP/SFTP hostname, port, protocol (e.g., WebDAV, Amazon S3, Backblaze B2), and username, allowing users to reconnect to a server with a single double-click.
While highly efficient within the Cyberduck ecosystem, .DUCK files create a "vendor lock-in" catch. They utilize a proprietary XML structure that is incompatible with other popular FTP clients like FileZilla or WinSCP. If you migrate to a different client or share the file with a colleague who doesn't have Cyberduck installed, the file is effectively useless. Users often find themselves unable to extract the IP address or path details buried inside the file without installing the full software.
The most practical solution is converting the .DUCK file to human-readable TXT or XML. This exposes the raw data, allowing you to copy the host address and credentials for use in other applications. For system administrators and developers performing bulk migrations, converting to structured JSON is the ideal workflow to programmatically extract and import connection profiles into new environments.
Convert.Guru analyzes your DUCK file, detects the exact format, and lets you read the text inside.
Users also converted DUCKLOAD, DOCX, ODT, JPG, PDF, XDC, PCG and PP3 files.
If you want to convert DUCK file to INI, CFG, CONF, CONFIG, JSON, XML, YAML, YML, TOML, ENV, PROPERTIES or RC, you can use Cyberduck or similar software from the "Server Connection Bookmark" category. In the File menu, look for Save As… or Export….
To convert ZSHRC, CONF, RCFILE, GITCONFIG, RC, PLIST, BASHRC, CONFIG, PROFILE, INI, PREFS or CFG files to DUCK, try Cyberduck or another comparable tool in the "Server Connection Bookmark" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DUCK converter.
