Jim Schwartz <jsch...@sbcglobal.net> added the comment:

when I run the following command:

python "H:\Users\LindaJim\Documents\AWS Python Learning\test_dir_scan_dir.py" 
"C:\\"

I get this output:

...

when I run the following command:

python "H:\Users\LindaJim\Documents\AWS Python Learning\test_os_walk.py" "C:\\"

I get this:

...
file is  C:\winutils\bin\winutils.exe
End time is  2021-12-15.13:11:54
Duration is  0:06:05

I don't think this should happen, right?
