IDA Pro叠加文件（Overlayed files）

 　Some EXE files are built with overlays.This means that the whole file is not loaded into the memory at the start of the program,but only a part of it.Other parts are loaded by the program itself into the dynamic memory or over some subroutines of the program.This fact leads to many difficulties when you disassemble such a program.

 Currently,IDA knows about overlays created by Borland and Microsoft C and Pascal compilers.

 中文翻译如下：

 一些EXE文件是用覆盖构建的。

 这意味着整个文件是开始时未加载到内存中程序，但只是其中的一部分。其他部分由程序本身加载进入动态内存或一些程序的子程序。这个事实导致很多困难，当你反汇编这样的程序。

 目前，IDA知道由Borland和Microsoft C创建的覆盖和Pascal编译器。
