What is a DUCK file?

DUCK files mostly belong to Cyberduck. DUCK files serve as connection bookmarks used by Cyberduck. They store server details like address, username, and protocol settings in an XML format.

The structured XML lets Cyberduck import and export your connection profiles easily.

They work for protocols such as FTP, SFTP, and WebDAV.

FilExt.com note: You can open these files with any text editor if needed. For additional details, visit Cyberduck official site.

How to open a DUCK file

DUCK format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the DUCK files looks like this:

The DUCK file extension is not widely used. Such a file is mainly used by one program with a specific format. The following file formats are most commonly found in DUCK files:

• 80% of all DUCK files save the data in XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The contents of these files are easily readable with a text editor. The files are on average 580 bytes in size and range from 360 bytes to 640 bytes. The file type is a fairly new file format. The keywords <dict>, <?xml version="1.0" encoding="UTF-8"?>, <plist version="1.0">, <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> and Protocol are typical for these files. The following filename is common: envicloud.duck. Files like these are about mybigcommerce, store, secure, cyberduck and admin.
• 4% of all DUCK files save the data in JFIF file format. JFIF is short for JPEG File Interchange Format. It is a bitmap graphic that uses JPEG compression. They consist of illegible, cryptic characters. The files are often between 140 KB and 370 KB in size. The keywords 8BIM, JFIF and Photoshop 3.0 are typical for these files.

All the rest of the DUCK files (16%) have different formats. These files are often connected to supprecovery, torguard, email or docx. If you want to find out what your DUCK file contains, drag and drop it onto this page.
