PE Explorer is the most feature-packed program for inspecting the inner workings of your own software, and more importantly, third party Windows applications and libraries for which you do not have source code.
PE Explorer lets you open, view and edit a variety of different 32-bit Windows executable file types (also called PE files) ranging from the common, such as EXE, DLL and ActiveX Controls, to the less familiar types, such as SCR (Screensavers), CPL (Control Panel Applets), SYS, MSSTYLES, BPL, DPL and more (including executable files that run on MS Windows Mobile platform).
PE Explorer gives you the power to look inside these PE binary files, perform static analysis, reveal a lot of information about the function of the executable, and collect as much information about the executable file as possible, without executing it.
PE Explorer leaves you with only minimal work to do in order to get an analysis of a piece of software. Once you have selected the file you wish to examine, PE Explorer will analyze the file and display a summary of the PE header information, and all of the resources contained in the PE file. From here, the tool allows you to explore the specific elements within an executable file.
