There is only one file type that uses the .LESS extension:
LESS Style Sheet
Webpage style sheet used by LESS, a dynamic style sheet language that extends standard CSS with features such as variables, mixins, operations, and functions; requires the LESS JavaScript library (less.js) to be included in the head section of the HTML page in order for styles in referenced LESS files to be processed.
