You will have to use the IShellFolder interface for that.  Use 
SHGetDesktopFolder() to get the IShellFolder for the top-level Desktop 
namespace, then use its ParseDisplayName() and BindToObject() methods to get 
the IShellFolder for the specific folder that you want to begin searching 
from, then use that IShellFolder's EnumObjects() method to enumerate its 
subfolders and files.  For each subfolder, call the parent IShellFolder's 
BindToObject() to get the IShellFolder for the subfolder, then call its 
EnumObjects() method, repeating recursively as needed.  For example:

    void SearchFolder(IShellFolder *ParentFolder, LPITEMIDLIST 
pidlSubFolder)
    {
            IShellFolder *SubFolder = NULL;
            if( SUCCEEDED(ParentFolder->BindToObject(pidlSubFolder, NULL, 
IID_IShellFolder, (LPVOID*)&SubFolder)) )
            {
                IEnumIDList *Enum = NULL;
                if( SUCCEEDED(SubFolder->EnumObjects(NULL, SHCONTF_FOLDERS | 
SHCONTF_NONFOLDERS, &Enum)) )
                {
                    LPITEMIDLIST pidlItem;
                    while( Enum->Next(1, &pidlItem, NULL) == S_OK )
                    {
                        // compare pidlItem to your search criteria as 
needed,
                        // such as by calling 
SubFolder->GetDisplayNameOf(pidlItem, ...)
                        // and other IShellFolder methods to get information
                        // about the current item...

                        ULONG ulAttr = 0;
                        if( SUCCEEDED(SubFolder->GetAttributesOf(1, 
&pidlItem, &ulAttr)) )
                        {
                            if( ulAttr & SFGAO_FOLDER )
                                SearchFolder(SubFolder, pidlItem);
                        }

                        CoTaskMemFree(pidlItem);
                    }

                    Enum->Release();
                }
                SubFolder->Release();
            }
    }

    {
        IShellFolder *Desktop = NULL;
        if( SUCCEEDED(SHGetDesktopFolder(&Desktop)) )
        {
            ULONG eaten = 0;
            LPITEMIDLIST pidlFolder = NULL;

            if( SUCCEEDED(Desktop->ParseDisplayName(NULL, NULL, 
WideString("The starting path here"), &eaten, &pidlFolder, NULL)) )
            {
                SearchFolder(Desktop, pidlFolder);
                CoTaskMemFree(pidlFolder);
            }

            Desktop->Release();
        }
    }

Now there is an exotic problem with a non-obvious solution.  I'm keeping a 
copy of that one!

Pretty much everything in Windows is represented by ITEMIDLIST and 
IShellFolder, especially virtual/special folders that don't have physical 
filenames/paths, but also physical filenames/path are represented as well. 
So it is good to know what Windows is doing internally to access those kinds 
of things generically.

Thanks Remy

This looks just like, what I need.

One little error though.

This line:
if( SUCCEEDED(SubFolder->GetAttributesOf(1, 
		&pidlItem, &ulAttr)) )

Should be:
if( SUCCEEDED(SubFolder->GetAttributesOf(1, 
		(LPCITEMIDLIST*)&pidlItem, &ulAttr)) )

But of cource You know that..;-)

Thanks again 
Kind regards
Asger

Thanks for the link Mehmet

Combined with what Remy provided I think I got it now.

Kind regards
Asger
