The txss file extension is associated with LaTeX, a document preparation system created by Leslie Lamport and used on multiple platforms, including Microsoft Windows.
A txss file contains a document written in LaTeX. Its text and markup describe the document's structure and formatting, and LaTeX processes the source to produce a typeset document.
LaTeX remains widely used for technical, scientific, and academic documents. The extension identifies a LaTeX document associated with the Windows version of LaTeX, although the LaTeX system is also available on other platforms.
Use LaTeX on Microsoft Windows to process a txss file. The file can also be viewed or edited as plain text, but it must be processed by LaTeX to produce the formatted document.
LaTeX does not usually convert a txss file by changing its extension. Instead, it processes the LaTeX source and can produce formatted output such as a PDF document.
