The mass edit operation in Relativity is a feature that allows a user with the appropriate permissions to modify the field values for multiple documents or objects at the same time. Instead of editing documents one by one, a user can select a group of documents from a view and apply the same change—such as updating a coding field, assigning a reviewer, or changing a responsiveness designation—to the entire selection in a single action. This significantly improves the efficiency and consistency of the document review and coding process.

B. Deleting users is an administrative task performed in the Users tab, not a document-level mass operation.

C. Creating backups is a system-level administrative function managed through the Relativity infrastructure, not a document review feature.

D. Running OCR is a separate mass operation used to extract text from images, distinct from editing field data.
