File types with icons -- how to extract from registry?

[Stephan, MZ]

Hello,

I like to program a tool displaying the content of ZIP files together with
file type and the related icon.

I know the tool FileTypesMan which can display file types and their icons,
but I don't know how the tool is checking registry. If I check
HKEY_CLASSES_ROOT, I cannot differ between real file types and other non-file
type information.

So, does someone know how I can determine file types and related icons in
order to display a list with file names and this information in my program?

Yours
Stephan
