Sending files via email was easy years ago when attachments were small in size. Today, the files we send are very large. We send all types of digital media and rich text documents. In order to keep network bandwidth and server storage minimized, most modern email servers limit the maximum file attachment to a certain reasonable size. In addition, many email servers reject files in their common native formats such as Microsoft Office documents, executables, and picture files due to fear of virus infections. DirectXchange safely transmits large files via email all in the convenience of Microsoft Outlook.
