I haven't used globMatch, but I've used nested dirEntries 
wildcard expansion loops.

I used SpanMode.shallow parameter with dirEntries to limit 
matches to one directory level.

I don't change directories with cd.  I just create a list of 
matches for the first level partial match, then create an inner 
loop that concatenates the matches from the first partial match 
and calls dirEntries again.


Here is a link to some code for the wildArgv single level search 
that I'm using.

This is roughly how I was using it, related to your example

	string[] argv;
	argv ~= r"c:\partial*";
	foreach( dirn; wildArgvs(argv[0..$])){
		string[] argv2 = null;
		argv2 ~= dirn ~ r"\path\*.d";
		foreach( filen; wildArgvs(argv2[0..$])){
                    do something with filen
                 }
         }
