Redwood Resource Extractor is a tool specialized in visualizing and extracting resources embedded in Windows executable files (EXE, DLL, OCX, CPL) and other 32-bit and 64-bit PE formats. It displays embedded resources in a hierarchical structure organized by language and type, allowing selective extraction of components.

• Hierarchical resource browsing. Presents all resources contained in PE files using a tree structure classified by resource type and associated language, facilitating navigation in complex files.
• Graphic resource preview. Displays images in BMP, PNG, JPG formats, icons at all resolutions including 256x256 pixel PNG formats, cursors, and AVI sequences directly in the interface without requiring additional software.
• Non-graphic resource visualization. Provides a structured representation of string tables, dialogs, version information, and menus, displaying content in readable format with Unicode and ANSI encoding.
• Full resource extraction. Allows saving any identified resource from the PE file to disk, maintaining its original format and binary structure.
• Advanced icon export. Extracts icon sets with all available resolutions, including high-resolution versions in PNG format, preserving transparency and color profiles.
• String table conversion. Exports complete textual content to external files in Unicode and ANSI formats, preserving the original structure and allowing its use in localization processes.
• Version information analysis. Extracts and displays version metadata embedded in executable files, including build numbers, copyright information, and product details.
• Binary dump mode. Provides a hexadecimal view for unrecognized resources or custom formats, allowing detailed technical analysis at the byte level.
• Dual architecture support. Works with both 32-bit and 64-bit PE files, including files with multiple resource sets for different platforms.
• Unified interface. Combines a structural navigation panel and a display area in a single window, optimizing workspace for browsing and extraction operations.
• Windows Explorer integration. Allows dragging and dropping executable files directly into the interface for immediate analysis, streamlining workflow.
• Batch export. Supports the simultaneous extraction of multiple selected resources to specified locations, automating the recovery process for embedded elements.

Redwood Resource Extractor was developed by Stefan Ziegler as part of the The-SZ tool suite. Its first version was published in 2010 as a specialized solution for software developers and analysts requiring access to embedded resources. The program is written in C++ with emphasis on accurate analysis of PE structures. It uses native Windows APIs for resource handling and proprietary algorithms for interpreting complex graphic formats. The software architecture allows processing files without modifying their original content.
