<div class="markdown_content"><p>Correct me if I am wrong, but the *23 libs are, as far as I have understood, Codesys 2.3 backward compatible libraries for use in codesys 3.5. </p> <p>You will need these whenever you convert old v23 projects to v35. After converting the project, you can then phase them out for more contemporary libraries if you wish.</p></div>

<div class="markdown_content"><p>Hello together</p> <p>I see in the standard libraries of codesys exist 2 libraries which have filehandling code in it and do more or less the same.<br/> There is one in SysFile S3 and one from "CAA Technical Workgroup" which has also S3 in its author name.</p> <p>Which one should be used for what reasons?</p></div>
