My website is currently using the magic fields plugin which creates a "files_mf" directory within the wp-content folder. I've setup my CDN and added that directory in the custom list. I'm able to upload all my files (including all the contents within the files_mf directory) to my CDN by using the upload feature with no issues.
The plugin only seems to be replacing my site's hostname (CNAME) properly for all media files located in the "\wp-content\themes" and "\wp-content\uploads" directory. is possible to do this with all of my other media files located in the "wp-content\files_mf" directory?
