DeNIST is a standard feature in Relativity Processing that filters out files based on the National Institute of Standards and Technology (NIST) list. The NIST list contains hash values for millions of known, common system and application files (e.g., .dll, .exe files from operating systems like Windows). By enabling the DeNIST option in a processing profile, Relativity compares the hash values of files in a data set against the NIST list and automatically removes exact matches from the discoverable document set, reducing irrelevant data for review.

A. OCR (Optical Character Recognition) is a feature that extracts text from images or non-textual PDFs, making them searchable; it does not remove files.

C. Clustering is an analytics feature that groups conceptually similar documents together; it does not filter files based on a predefined list.

D. Branding is a production feature used to apply Bates numbers and other endorsements to images; it is unrelated to file filtering during processing.
