C#-Enumerate all logical and virtual drives-folders from desktop

[Bruce Cleaver]

Hello,
I've been trying to find a way to enumerate all drives- logical and virtual starting at the desktop for an explorer clone. I know how to get the logical drives and icons, but have not found a way to get all the drives and folders.
I think IShellFolder with enumobjects is used but I can't find an example.
Thank you for your help.

Heya, Bruce. Welcome to TSDN!

We don't really have a D-flat forum here, but I'll go ahead and move your post to the .NET forum, where one of our resident Experts should be able to help you out.
