GETTING STARTED GUIDE I LAW PREDISCOVERY
Alternately, you can perform deduplication earlier—during the ED Loader
import process described previously in the section “Walk-through—Building the Case”:
1. Select File > Import > Electronic Discovery from the main menu to open the ED Loader.
2. Click the Settings tab and select Deduplication from the side menu to reach the list of available options.
3. Click the checkbox to enable duplicate detection.
4. Select the working digest you want to use. This is the method of hashing that will be used
to determine duplicates. The hash values are obtained through metadata fields (email)
or by hashing the entire file (e-docs). LAW PreDiscovery uses two types of hashing methods:
a. MD5: 128-bit output
b. SHA-1: 160-bit output
5. Now, select the Test to deduplicate against (Scope). During the import process, deduplication
can be performed at one or two levels. Select Case Level (Globally) if you want to deduplicate
documents against the entire incoming collection and against existing records in the LAW
PreDiscovery case. Select Custodian Level if you want to deduplicate documents against records
with identical custodian values.
6. Next, you will need to select an action from the pull-down list under “If record is considered
a duplicate then (Action).” Select Include if you would like to create a record for the duplicate
in the database and copy the native file into the case folder. Select Partially Exclude if you would
like to create a record in the database, but not copy the native file. Select Exclude if you do not
want to create a record and do not want to copy the native file to the case folder.
