Does anyone know what a sif file is and how it can be imported into an Access table

It can be a number of things, but I don't think any of them are something you can (or would want to) import into Access.

What is a SIF File? (http://filext.com/file-extension/SIF)

Look here - http://www.course.com/default.cfm This is the only thing I can see which might be relevant.
