File details and IShellFolder2

[brian.shapiro]

I've been looking for a way to find the file details shown in the
shell's property dialog, and I finally came across IShellFolder2,
which allows you to retrieve a list of the available columns. But I'm
also wondering if there's a way to find the group names the various
properties are put under. For example, in an MP3 file, the shell
groups the properties into categories of Description, Media, Audio,
Origin, Content and File. Does shell32.dll provide a means to get
these groups?

Also, if anybody could help, I'm also looking for an example of how to
implement IShellFolder2 and GetDetailsEx in C#.

Thanks in advance.
