What are CRL files and how to open them

Are you having problems opening a CRL file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CRL files.

What is a CRL file?

CRL files have multiple uses, and Calamus Ruler List is one of them. Read more about the other uses further down the page.

Calamus Ruler List

A .crl file, also known as a Calamus Ruler List file, is a text document used by the professional desktop publishing software Calamus for the Atari ST platform. It contains information about the rulers and grids used in a Calamus document, such as the unit of measurement, size and position of rulers, and visibility settings.

The .crl file stores the settings for rulers and grids so that users can save them for reuse in different documents. With these settings, rulers can measure and align elements in a document to ensure accuracy, while grids act as references for positioning elements.

Calamus is an older software that is no longer widely used, so it's important to note that .crl files may not be compatible with modern desktop publishing programs.

How to open CRL files

Important: Different programs may use files with the CRL file extension for different purposes, so unless you are sure which format your CRL file is, you may need to try a few different programs.
