About .tre Files

TRE files are used for two distinct purposes.
Some TRE files follow the text/x-tre MIME type. They are plain text files created by SequoiaView that store directory tree information. You can open these with a simple text editor or SequoiaView itself.
Other TRE files use the application/octet-stream MIME type. They are binary archives used by Jane's Longbow 2 to hold game data. These files are managed internally by the game engine or compatible modding tools.
According to FilExt.com, the same file extension can mean different things based on its context.

SequoiaView Directory Tree - A text file that records folder hierarchies. It is useful for visualizing disk usage.
Jane's Longbow 2 Data Archive - A binary file that contains game data. It is essential for the game’s operation.

Use the appropriate software to view or edit each type of TRE file.

Relationship between file extension and MIME type

A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.

File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.

File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why can one extension have multiple MIME types?

Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
