About NAV files
A .NAV file most commonly contains navigation mesh (NavMesh) data used by bots in games built on the Valve Source Engine, such as Counter-Strike or Left 4 Dead. It dictates where AI characters can walk, jump, and hide on a specific map. Alternatively, a .NAV file can be a RINEX Navigation Data File used for GNSS satellite data tracking, a GPS track log from OziExplorer, or a video recording index for Digital Video Recorders (DVRs). The main disadvantage of .NAV files is their extreme fragmentation. Source engine NavMeshes are proprietary binary files that are completely unreadable outside of a game engine or map editor. DVR .NAV files are merely metadata for video streams, entirely useless without the accompanying .TS or .MP4 video. RINEX .NAV files are dense ASCII text files that are hard to visualize without specialized scientific tools. For game modding, .NAV files are rarely converted; they are edited directly in-game. However, for RINEX files, researchers often convert them to .CSV or .JSON for data analysis. For GPS tracks, converting .NAV to .GPX or .KML allows viewing in Google Earth.
Convert.Guru analyzes your NAV file, detects the exact format, and lets you read the text inside.

The NAV Converter Story
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 NAV converter.
