[python-win32] filling Windows properties "Summary" tab?

[aurora]

I am reading the discussion of "filling Windows properties "Summary" tab?"

I too am interesting in finding out a way to read and write the summary  
propreties. It isn't very clear for me from the thread that what classes  
of if there are any sample program I can use. A more basic issue is I  
would like to write some meta data for any kind of files (even for folders  
if possible). There are mention of COM "structured storage" files like MS  
office documents. However I am able to set this for a simple text file. On  
the other hand this summary is not available if I rename it to .html. Much  
appreciate if you can help me to understand this.

Thanks,

wy
