Extract text from Cyberduck bookmarks (DUCK)
To convert DUCK bookmarks to another format, you need Cyberduck or other Settings software.
To convert other file formats to the "Connection Bookmark File" file type, you need software like Cyberduck or a similar tool.
A .DUCK file is a connection bookmark created by Cyberduck, a popular open-source FTP and cloud storage client for macOS and Windows. These files store server credentials, including the protocol (like FTP, SFTP, WebDAV, or Amazon S3), hostname, username, port, and directory paths.
Users typically open these files directly in Cyberduck or Mountain Duck to initiate a server connection. However, the .DUCK format is a proprietary implementation. While it uses standard XML structuring under the hood, the specific tags and schema are unique to the software.
You may need to convert a .DUCK file if you are migrating to a different FTP client like FileZilla or WinSCP, which use their own proprietary bookmark formats. The main disadvantage of the .DUCK format is its lack of portability between different software ecosystems. Furthermore, for security reasons, Cyberduck does not store passwords inside the .DUCK file; it relies on the macOS Keychain or Windows Credential Manager. This means any conversion will permanently omit the password.
The most practical conversion targets are XML, CSV, or plain TXT. Converting to these formats allows you to extract the server addresses, usernames, and ports into a readable list or spreadsheet for manual entry into your new software.
Because .DUCK is a specialized settings file, standard online converters often fail to process it into a working profile for other FTP software. Only the original software can properly read or export the exact credential mappings. convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your file to see what it is and convert it if supported. Since our analysis detects the underlying XML format, viewing or text extraction is fully possible.
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 "FTP Connection Settings" 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 "FTP Connection Settings" 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.
