Explorer Suite
Current Version: III (18/11/2012)

Download the Explorer Suite

Small announcement: the CFF Explorer was started as a side project many years ago. While I will continue to release updates from time to time, it is not going through radical improvements. If your organization needs professional PE inspection (not editing), then you might take a look at Cerbero Profiler (the commercial product of my company), which properly supports many file formats beyond the complete Portable Executable specification.

In addition to that we also offer a completely free PE viewer for the community called PE Insider.
Cerbero Profiler

Created by Daniel Pistelli, a freeware suite of tools including a PE editor called CFF Explorer and a process viewer. The PE editor has full support for PE32/64. Special fields description and modification (.NET supported), utilities, rebuilder, hex editor, import adder, signature scanner, signature manager, extension support, scripting, disassembler, dependency walker etc. First PE editor with support for .NET internal structures. Resource Editor (Windows Vista icons supported) capable of handling .NET manifest resources. The suite is available for x86 and x64.

The CFF Explorer was designed to make PE editing as easy as possible, but without losing sight on the portable executable's internal structure. This application includes a series of tools which might help not only reverse engineers but also programmers. It offers a multi-file environment and a switchable interface.

Also, it's the first PE editor with full support for the .NET file format. With this tool you can easily edit metadata's fields and flags. If you're programming something that has to do with .NET metadata, you will need this tool. The resource viewer supports .NET image formats like icons, bitmaps, pngs. You'll be able to analyze .NET files without having to install the .NET framework, this tool has its own functions to access the .NET format.
