File type: Document file
A .t file is an unformatted manual page for the roff/troff document processing system. It contains text and formatting requests that troff uses to produce a formatted manual page.
The format is associated with Unix and Unix-like operating systems.

The .t file extension is associated with troff, a Unix document processing system originally developed by AT&T Corporation. Troff processes roff input files to format documents such as manual pages.
A .t file contains the unformatted text of a manual page together with roff/troff commands that control its layout. It is a text-based input file rather than a finished, typeset document.
Troff and compatible implementations are available on Linux and other Unix-like systems, including FreeBSD and NetBSD. The extension is considered obsolete, although roff-based manual-page processing remains available on many Unix systems.
MIME type:
application/x-troff
Open a .t file with a text editor to read its manual-page text and roff commands. To format or view the page, process it with troff or a compatible roff implementation such as groff on Linux, FreeBSD, NetBSD, or another Unix-like system.
Process the file with troff or groff to produce formatted output. Depending on the implementation and selected device, the output can be prepared for terminal display or generated in formats such as PostScript or PDF.
There is no general need to convert the original file if the goal is to edit the manual page, because it is text-based. Keep the roff source when further editing or reformatting is required.

The Timber file extension is associated with Timber, a general-purpose programming language designed for constructing complex event-driven systems.
Timber programs can be structured as objects and reactions. Platform-independent timing constraints provide precise control over the real-time behavior of reactions, making the language suitable for specifying and implementing real-time embedded systems.
A .t file contains Timber source code. The Timber compiler processes the source file as part of building a Timber program; it is not itself a compiled program.
A .t file is a plain-text source file, so it can be opened, read, and edited in any text editor. A source-code editor may provide better handling of Timber syntax.
To build or run the program, open the file with the Timber compiler and any other required project files or build configuration.
Timber source code is not normally converted to another file format. The Timber compiler should be used to compile the .t file into a program for its target system.

The t file extension is associated with the Turing a Pascal-like programming language named after British computer scientist Alan Turing.
Developed in 1982 by Ric Holt and James Cordy, then of University of Toronto, Canada.
Turing is a descendant of Euclid, Pascal and SP/k that features a clean syntax and precise machine-independent semantics.
Turing is used primarily as a teaching language at the high school and university level.
In November 2007, Turing, which was previously a commercialized programming language, became freeware.
Use compatible tools to work with *.t files.
Possibly can be compiled to other formats.
