==导言==
WIN-NE可执行格式，专为Windows 3.x设计、称为“NE”或“New Executable”格式。同样是16位格式，它去除了[[MZ]]格式的最大大小限制。

==Support==
使用它的操作系统：Windows 1.01到3.xx。
该格式'''can'''在以后的32位windows系统（在VDM中）上运行，但不是本机格式<br/>
由于v8086缺少64位，因此放弃了对64位windows的支持。

==概述==
===DOS存根===
DOS存根是有效的[[MZ]]exe。这使开发者能够打包MS-DOS和Win16版本的程序，但只打印“此程序需要Microsoft Windows”。 e_lfanew字段（偏移量0x3C）指向NE报头。

===NE文件头===
NE报头是一个具有多个特征的相对较大的结构。由于格式年代久远，有些项目的含义不清楚。结构如下（有些注释可能是错误的）。 If so please change):
