WholeClear Investigator is a powerful desktop tool utilised by digital forensic analysts, eDiscovery professionals, corporate compliance officers, and teams responding to incidents on Windows systems. The application can deeply analyse many types of email stores, documents, photos, folders, and backups. It supports multiple email formats such as PST, OST, EML, EMLX, MSG, MBOX, and NSF. But NSF files require Lotus Notes to be configured to process them. Users can view message headers, content, attachments and routing pathways of communications. Users can search indexed evidence using Boolean operators, phrases, field filters, wildcards and regular expressions. Additionally, the software provides tools to visualize communication patterns and sender-recipient interactions through dynamic graphs. It carefully records SHA-256 hashes, detects processing irregularities, documents audit details, and preserves chain-of-custody information for accountability. Users can easily export case results and reports in numerous formats such as CSV, Excel, JSON, HTML and PDF for additional analysis or documentation. Additionally, the OCR functionality allows extraction of text from scanned documents.
