You can share files with non-Quatrix users with the selected Public, Tracked or Restricted share privacy option. If the selected share privacy option is Public, your recipients get the link that can be accessed through their browser without logging in to Quatrix. To share files with the Tracked or Restricted privacy, users should be registered in Quatrix as contacts. See more information about Contacts here.
