I have downloaded the Sage 50 accounting 2015.0 software. however for my online course I need the SageData15 folder and files to do my assignments. I have searched on my computer for .sai and .saj but the only files that appear are "universal". The sagedata15 folder is no where to be found. I have looked at the student forum but still have not found the solution to my problem.

The textbook I am using is called "Using Sage 50 Accounting 2015 By: M Purbhoo. Copyright 2016 Pearson Canada. 

Any help would be much appreciated, Please kindly advise.
