UEFIFind, which uses ffsParser to find image elements containing a specified pattern.

Jethro Beekman's tree utility can be used to work with the extracted tree. UEFIExtract, which uses ffsParser to parse supplied firmware image into a tree structure and dumps the parsed structure recursively on the FS.There are some other projects that use UEFITool's engine: The missing parts are in development and the version with a new engine will be made as soon as image reconstruction works again. Editor part, i.e image reconstruction routines.It's in development right now with the following features still missing:

In the beginning of 2015 the major refactoring round was started to make the program compatible with newer UEFI features including FFSv3 volumes and fixed image elements. Project development started in the middle of 2013 because of the lack of cross-platform open source utilities for tinkering with UEFI images. UEFITool is a cross-platform open source application written in C++/Qt, that parses UEFI-compatible firmware image into a tree structure, verifies image's integrity and provides a GUI to manipulate image's elements. More information on UEFI is available on UEFI Forum official site and in Wikipedia. In 2015 there are numerous systems using UEFI-compatible firmware including PCs, Macs, Tablets and Smartphones on x86, x86-64 and ARM architectures. The first EFI-compatible x86 firmwares were used on Apple Macintosh systems in 2006 and PC motherboard vendors started putting UEFI-compatible firmwares on their boards in 2011. Unified Extensible Firmware Interface or UEFI is a post-BIOS firmware specification originally written by Intel for Itanium architecture and than adapted for X86 systems. UEFITool is a viewer and editor of firmware images conforming to UEFI Platform Interface (PI) Specifications.
