Types of ESI

Examples of the types of data included in e-discovery are e-mail, instant messaging chats, documents, accounting databases, CAD/CAM files, Web sites, and any other electronically stored information that could be relevant evidence in a law suit. Also included in e-discovery is "raw data", which Forensic Investigators can review for hidden evidence. The original file format is known as the"native" format. Litigators may review material from e-discovery in one of several formats: printed paper, "native file,", PDF format, or as single- or multi-page TIFF images.
