• More free storage for new users – New users now get 100GB totally free for one year. With SurDoc, there are no limits on file sizes.
• Free upgrade for existing users – To reward existing users' loyalty, SurDoc is also automatically upgrading all current users to 100GB for the remainder of their first year.
• Adding sync – Now changes made to a file on one device will appear in that file across all of the users' devices. Sync is especially valuable as SurDoc allows unlimited computers, tablets and smartphones per account.

The feature-rich service already included file sharing via links, email and social media, public folder, document signing, superior VisiDoc™ viewing, and more. These features are all included at no extra charge.
