Native Extraction+

Prepare Email and Native Files for Load into Relativity™, Concordance™, Lexbe, or Other Native Review Platform

Lexbe’s Native Extraction+ service prepares your case data for native or near native review in litigation databases like Relativity and Concordance.

Our Native Extraction+ service works by inputting raw native file versions and flattening any attached files from container files, like an .msg file, and extracting file metadata. In the case of Outlook .ost and .pst files, that means taking each .msg file and opening and extracting data from any attachments.

The end result of this process are extracted native files with an associated native load file. This loadfile allows you to easily put your documents into your native or near native review platform where they can be reviewed, stored, bates stamped, and produced.

We can deliver the processed data to you via secure FTP download link (size limitations), on HDD/flash drives and/or upload to the Lexbe eDiscovery Platform review system. In each instance, processed files are stored as one or several RAR container files to allow spanning multiple drives, increase transfer speed and facilitate quality control procedures.
