添加文件到NK.bin的方法

jim900os 2008-05-04 11:04:55
.BIB文件用于确定Windows CE映像中的目标模块、组件和文件。
.BIB文件包含4个部分:FILES、MODULES、MEMORY和CONFIG。

一、FILES部分:
FILES分配一部分内存空间给静态数据文件。
此部分文件格式一般为:字体文件.TTF、文本文件.TXT、位图文件.BMP和声音文件.WAV等。
例如:
;Name Path Memory Type
;------ --------------------------------------- ----------- -----
Tahoma.ttf $(_FLATRELEASEDIR).ttf NK SHU
Name:在Windows CE系统中的文件名。
Path:文件在开发工作站中的位置。
Memory:文件所属的内存区。
Type:定义文件属性。
Windows CE中的文件有以下文件属性:S为系统文件、H为隐含文件、U为非压缩文件、R为压缩资源文件、C为压缩文件。1个文件可以同时具有几种属性。
