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
}
}
