Supported file types in eDiscovery (Premium)

2025-09-02

Important

The classic eDiscovery experiences were retired on August 31, 2025. This retirement includes classic Content Search, classic eDiscovery (Standard), and classic eDiscovery (Premium). These options aren't available as an experience option in the Microsoft Purview portal.

Unless you're working directly with Microsoft when using these legacy features for specific short-term transition scenarios, use the guidance for the new eDiscovery experience in the Microsoft Purview portal.

Microsoft Purview eDiscovery (Premium) supports many file types at many different levels. The following tables in this article list the currently supported files types.

These tables indicate if a file type is supported for text extraction (and Optical Character Recognition or OCR text extraction for image files), viewable in the native viewer, and also supported in the Annotate viewer in eDiscovery (Premium).
