Write a file's summary information

If you right click on a file in explorer and select properties, a property page appears and you can select the summary tab and edit a description.

What is the correct way to do this programatically? I tried StgOpenStorage - but this does not work. (It works only for files which are MS Office documents not for files where you have added a description using windows explorer).

Thanks in advance for any help
