The sur file extension is associated with Freelancer, a space trading and combat simulation game developed by Microsoft for Windows.
A sur file contains three-dimensional collision zone data used by the game to determine collisions with objects and parts of the game environment. It is a game-support file rather than a general-purpose 3D model or exchange format.
The format is specific to the Windows version of Freelancer and is primarily of interest when working with the game's files or creating modifications.
A sur file is normally read automatically by Freelancer and is not intended to be opened as a document. There is no standard Windows application for viewing its collision data directly.
Users working on Freelancer modifications need a tool or workflow designed for editing the game's files. Avoid changing or renaming the file unless the modification requires it, because the game may no longer be able to use the associated collision data.
A sur file has no standard conversion to a general 3D or document format. Its collision data is intended for use by Freelancer, not for interchange with other applications.
When a modification changes the relevant game geometry, a replacement collision file is normally created through a Freelancer modding workflow rather than converted for use in another program.
