Message378603
Hi,
I would like to report bug for os.makedirs().
I am running this script on Windows 10 1909 (most win10 work), python 3.8.1.
os.makedirs() is making explorer.exe huge amount of memory and crashing the system after only 3 hours.
After changing that line to subprocess.run('mkdir ...') memory usage is reduced significantly.After changing all shutil functions as well, memory usage will not grow.
(This is my first time community contribution. If anything, please let me know.)
