I am not sure about your question. With DriveHQ FileManager client software (or just logging on to DriveHQ.com website), you can right click on a folder/file and select Share. You can then enter usernames or email addresses in the Share-to box. After you share a folder, the system automatically generates a Share Notification email. Recipients can click the link in the email to access the shared folder.
DriveHQ supports more advanced file sharing, e.g. you can share different folders with different users/subgroups/contact groups. You can set different share permissions. You can also publish a folder or static website (for paid members and True members). You can also create a True Drop Box folder for anybody to upload files to you without an account.
