File Type 1LaTeX Document Class File
What is a CLS file?
File written in LaTeX, a document markup language often used for typesetting academic papers; stores a class with a predefined typeset configuration that can be imported into a .TEX document; used for storing templates for articles, forms, and other types of documents.
Class files help users generate documents with the same style and structure. For example, a scientific journal publisher may distribute a CLS file to submitting authors so that all articles appear the same in the publication.
LaTeX software installations typically include some CLS files that can be used as document templates.
