An attachment is a record or file associated with another record for the purpose of storage or transfer. There may be multiple attachments associated with a single “parent” or “master” record. The attachments and associated record may be managed and processed as a single unit. In common use, this term refers to a file (or files) associated with an e-mail for transfer and storage as a single message unit. Because in certain circumstances the context of the attachment—for example, the parent e-mail and its associated metadata—can be important, an organization should consider whether its policy should authorize or restrict the disassociation of attachments from their parent records.
