Extract text from navigation data files (CDN)
To convert CDN navigation files to another format, you need Jeppesen FliteDeck Pro or other Data software.
To convert other file formats to the "Flight Procedure Data File" file type, you need software like Jeppesen FliteDeck Pro or a similar tool.
The .CDN file extension is an aeronautical navigation procedure data file. It stores critical flight path, waypoint, and procedural data for commercial and general aviation software. Pilots and airlines rely on these files within electronic flight bag (EFB) applications to display digital charts and navigation databases in the cockpit.
The primary software used to open and process these files is Jeppesen FliteDeck Pro. Jeppesen, a Boeing company, creates and distributes these files as part of their global aeronautical information services.
Users often struggle with .CDN files because they are strictly proprietary. The format requires a paid, commercial subscription to open or update. You cannot natively view a .CDN file in standard web browsers, text editors, or GIS tools. The data is often compressed or obfuscated to prevent tampering and ensure strict aviation safety compliance.
Standard online converters usually fail to process .CDN files because the format is closed and lacks public documentation. Generally, only the original Jeppesen software can properly read, update, or export the aeronautical data into standard formats like PDF or CSV. However, convert.guru can still identify the file format, inspect the file, and show plain text or internal metadata. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible. Just drag and drop your file to see what it is and convert it if supported.
Convert.Guru analyzes your CDN file, detects the exact format, and lets you read the text inside.
Users also converted 00000000, ZIP, MP4, PNG, M3U8, IPT, ZDL, ZDP, AVERY, CIA and PKR files.
If you want to convert CDN file to CIA, PKR, MP4, AVI, MOV, WMV, FLV, WEBM, MKV, M4V, 3GP or OGV, you can use Jeppesen FliteDeck Pro or similar software from the "Aeronautical navigation data storage" category. In the File menu, look for Save As… or Export….
To convert MTS, MOV, RMVB, DIVX, RM, H264, TS, WMV, VOB, MP4, XVID or AVI files to CDN, try Jeppesen FliteDeck Pro or another comparable tool in the "Aeronautical navigation data storage" 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 CDN converter.
