No. `fs.globStatus` Return all the files that match filePattern and it will
not dive into the nested folder.
Say folder structure looks like following
/root
..../Jack
......../subDir1
......../JackFile1
..../Rose
......../subDir1
......../subDir2
......../RoseFile1
..../file1
Case 1: `/root/Jack/subDir1` it will monitor any new files added into
exact "/root/Jack/subDir1" if "JackFile1" is a new added file, it's NOT in
scope.
Case 2: `/root/Jack` it will monitor any new files added into "/root/Jack"
folder. New files added into "/root/Jack/subDir1" is NOT in scope.
Case 3: `/root/*/subDir1` it will minitor any new files added into both
"/root/Jack/subDir1" and "/root/Rose/subDir1".
Case 4: `/root/Rose/*` it will monitor any new files added into
"/root/Rose/subDir1" and "/root/Rose/subDir2".
