[h-e-w] Emacs 23 cann't open a file under a very long path.

[hongyi . zhao]

Dear all,

I use the GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600) of 2008-07-26 on 
LENNART-69DE564.  I find that when I want to open a file under a very long 
path, say:

---------------------
F:\zhaohs\Desktop\博士论文工作相关\博士论文写作相关\我的修改过程等细节\一些进一步的修改\解决多文献列表问题，已经接近实际所用（目前所用方案）\如何产生多个参考文献列表\基于multibib的实现\cjk_preamble_werner\werner最后提供的方法,必须使用utf8编码\cjkbib\cjk_preamble.tex
 
--------------------- 

The Emacs will give me errors like the snapshot I posted here in the attachment.

But, if I rename the above file into cjk.tex, in this way, the above path will 
look like the following:

-----------------------
F:\zhaohs\Desktop\博士论文工作相关\博士论文写作相关\我的修改过程等细节\一些进一步的修改\解决多文献列表问题，已经接近实际所用（目前所用方案）\如何产生多个参考文献列表\基于multibib的实现\cjk_preamble_werner\werner最后提供的方法,必须使用utf8编码\cjkbib\cjk.tex
 
-----------------------

Then the Emacs will open the above file correctly.  

Why does this happen?  Who can give me some hints?

Regards,
