FEX Core SDK

Forensic-grade image and filesystem access, exposed as a flat C-style DLL.

The SDK ships:

• FEX.Core.dll — the core engine. Win64 today; Linux64 and macOS arm64 follow.
• C# reference example — FexViewer, a console app that demonstrates the full V2 + V3 surface end-to-end. See the Quick Start.
• Documentation — function-by-function reference for every export, plus the concepts (buffer ownership, threading, error handling) you need to integrate cleanly. Start at the Documentation home.
• C# Reference — IntelliSense-extracted reference for the FexViewer example types, available from the C# Reference tab in the navbar.

If you're new, read the Quick Start and the V2 API reference in that order — that covers ~90% of typical integrations. Reach for V3 when you hit million-record datasets or only need a few columns.
