一种操作系统之上的可执行文件格式从许多方面反映了这种操作系统本身的情况。尽管研究可执行文件格式并不是大多数程序员的首要任务，但从中你却能够获得许多知识。在本文中，我要带你游历可移植可执行（Portable Executable，PE）文件格式，它是Microsoft设计用于所有基于Win32® 的系统，包括Windows NT® 、Win32s™ 以及Windows 95之上的可执行文件格式。在可预见的将来，PE格式会在Microsoft的所有操作系统中扮演重要角色，其中包括Windows 2000。如果你使用过Win32s或Windows NT，那么你已经使用过PE文件了。即使你只是使用Visual C++® 为Windows 3.1编写程序，你也使用了PE文件（Visual C++的32位MS-DOS® 扩展组件使用这种格式）。简而言之，PE格式已经深入到各种系统以及系统的各个角落，在将来不可避免要碰到它。现在是找出这种新型的可执行文件格式到底给操作系统带来了什么好处的时候了。-An operating system is on the executable file format in many ways reflects the situation itself of this operating system. Although the study is not the primary task of the executable file format for most programmers, but it can get you a lot of knowledge. In this article, I want to take you traveled portable executable (Portable Executable, PE) file format, which is designed for all Microsoft Win32® -based systems, including executable 95 over Windows NT® , Win32s ™　and Windows file format. In the foreseeable future, PE format will play an important role in all of Microsoft s operating system, including Windows 2000. If you ve used Win32s or Windows NT, then you have used PE files. Even if you just use the Visual C++ ®　write programs for Windows 3.1, you can also use a PE file (Visual C++ 32-bit MS-DOS®　expansion modules using this format). In short, PE format has penetrated into every corner of the various systems and systems in the future inevitably encounter it.
