Within the description of one of the categories there needs to be a link to download a file. Is there a way to do this in the WYSIWYG editor?

Yes, click on HTML icon on WYSIWYG editor toolbar and put your link to the download file and save. Alternatively, you can disable WYSIWYG editor from
Administration > Configure > Store > General and put your HTML directly to the category description filed.

Thank you. Is there a way for the client to use the admin and link to a file without FTP access?

You can upload a file from Asset Manager (Administration > Catalog > Categories > Images and Assets) and then add a link to the file for download inside category description something like this:
NOTE: You can add a valid file extension (zip, txt, pdf etc.) from Administration > Configure > Security > System Settings

Hope this helps.

Yes, it does! Thank you!
