Here is a list of File Upload Sites you can link to. These sites have High DA and low Spam score. They have been carefully selected for postive SEO practices, enjoy!

Remember, you cannot just build a link and leave it there. Google WILL ignore your link, your account must be active, try posting at least 2 times per month to have the link indexed properly by Google. Do not add multiple articles around only one link, it will look spammy. Add different website links around your articles, and even create articles without links.
