PE64

PE64 is a file format used for executable programs and object code on the Windows operating system. It is the 64-bit version of the Portable Executable (PE) format, which itself is derived from the Common Object File Format (COFF). The PE format defines the structure of files that are loadable by the Windows operating system.

The PE64 format is used for 64-bit applications and drivers. It contains various sections, including the code section (.text), data section (.data), and import/export tables, which allow the operating system to load and execute the program correctly. It also includes information for debugging and resource management.

Key components of the PE64 format include the DOS header, PE signature, COFF file header, and the optional header. The optional header contains crucial information such as the entry point of the program, the sizes of various sections, and the image base address. This structure enables the operating system to map the executable into memory and begin its execution.

The widespread adoption of PE64 is a direct result of the transition to 64-bit computing across the software industry. Most modern Windows applications and system components are distributed in this format. Understanding the PE64 structure is essential for reverse engineering, malware analysis, and compiler development.
