What is one use of E-Mail aside from communication?

E-mail serves as a valuable method for storing data because it allows users to keep records of communication, documents, and files within their inbox and sent items folders. This capability enables individuals and organizations to archive important information, access it later, and maintain a searchable database of correspondences and shared content.

While other choices like receiving audio files, processing graphics, and sending images are functions of e-mail, they do not relate to the core utility of using e-mail as a data storage solution. Data storage through e-mail can be particularly useful for retaining documentation like contracts, reports, and other important communications that need to be referenced over time.
