[Using the Resource Files in the Workbook]

i have tried to find these files with the "m"  and without.  i am familiar with how to unzip a file.  my problem is to find the working files.
the files for photo downloaded right away when i copied the link from this forum. But i cannot get connected to the files for designer or publisher.
 

New problem:
i started to work with the new photo v2.  it is problematic.  saved files cannot be opened in another software. (my painting progran) i tried saving as a psd.  or jpeg. 
or first saving as an affinity file and then trying to resave the file.  Any of the files saved in Affinity are not recognied in another software.  it simply
doesn't respond to it.
?!  i am in the middle of a project. The files are a problem.  Did I get a corrupted download?

 

[Using the Resource Files in the Workbook]

it is 2022.  I purchased all three workbooks when i bought the first version of affinity.
i would like to go through the resource files but cannot find them.  i am directed to 
https://www.affin.com/publishercoreskills and the files are unavailable.  i realize there are
youtubes.  but i learn better by "doing".  
i would think by now these files would be easily accessed.   How do i get the files?
