Deduplicating Documents

Deduplicating documents reduces the number of documents requiring review. You can remove duplicate documents in a document set ("deduplicate") using the Document List.

As you select duplicate documents to be removed, Post Deduplication displays the resulting document total.

To deduplicate documents

  1. On the Cull Document List, load the document set you want to deduplicate.
  2. Select the Matter with the documents you want to deduplicate.
  3. Select the Deduplication Type:
    • None: No duplicate files are removed.
    • Global: All duplicate files found in the entire data set are removed regardless of custodian. Global deduplication is also referred to as "across custodian" or "horizontal deduplication".
    • Custodian: Only duplicate files that were found within each custodian's data set are removed. Custodian deduplication is also referred to as "within custodian" or "vertical deduplication".
  4. To exclude documents included in prior promotions, select Ignore Promoted Duplicates
  5. To include related documents, such as attachments or documents contained within a compressed file type (zip, rar, etc.), select Include Family
