Deduplication
DISCO performs deduplication of data by calculating a metadata hash for emails, or the SHA-1 hash for non-email files. Deduplication is done at the family level and is global - there is no option to deduplicate at a custodial level. Learn more about Deduplication within DISCO.
Note that disabling this setting will prevent all documents in the ingest from being deduplicated against any current and future data.
Exception Handling
Ingest exceptions can be automatically routed to DISCO Professional Services for remediation and resolution. When this option is selected, charges will apply for the work to remediate files.
Hidden Content
DISCO provides the ability to render and display hidden content from a file when generating a document's Near Native view. Any selected hidden content is rendered on the near-native image and will be included on the image if that document is produced.

Emails can contain embedded HTML references to external files. This is the standard approach for showing photos or other content from the internet. When these emails are opened, the files are automatically retrieved and their content is displayed in the body of the email. Since almost all email users view these references as part of the email, most clients (including DISCO) will, by default, display this content; however, there are some scenarios where users would not want this content rendered.
One area of concern with this behavior can be "tracking pixels" - invisible images that are used primarily for marketing purposes to identify when an email is opened. By logging when and from where an image tracking pixel is requested, marketing systems can identify when an email was opened and by what IP address. To prevent this behavior, all external content must be blocked from being rendered. This blocking is what causes the below behavior in Outlook.
DISCO has included the ability to prevent this behavior by not rendering these external images. When this option is selected, ALL external content within emails processed this way will be represented by a red X filling the area of the image.
