Symptoms
Assume that you receive a message from a partner through the Microsoft BizTalk Accelerator for RosettaNet (BtaRN). If the message has one or more attachments (for example, a multi-part message where one or more parts are attachments), BtaRN saves each attachment to a file. However, each saved attachment may pointlessly show zero-bytes appended to the end of its actual content.
