Setting the File size filter to true in the ZyLAB.EDiscovery.Processors.PS.Deduplicator.dll.xml file causes a "path is null" error in Legal Processing.
File size filtering does not support meta data only
Please check the following setting in ZyLAB.EDiscovery.Processors.PS.Deduplicator.dll.xml:
<configuration id="Pre Tiff Producer (ZyXmlTiff Default)" priority="0" onlyMetaData="false">
Meta data only needs to be disabled for file size filtering to work. Be sure onlyMetaData="false".
