All digital evidence, whether emails, computer files, or text messages, comes with metadata. Metadata is nothing more than “data about data,” i.e. things your phone or computer keeps track of about a digital file. Some of the most common examples are the “last accessed date” (when a file was last opened) and its “creation date” (when a file was first created).
Great, so metadata exists. So what? I get this question all the time. Particularly from opposing counsel when I’ve demanded that he or she reproduce a set of documents with metadata, usually after he or she has already provided a PDF copy. But I’m not asking for metadata in a fit of gamesmanship or to drive up litigation costs. I do it because metadata can be as valuable as the content itself.
