How can we write code in Python​ to find all file system including files from root to each and every file of the current computer system.

You can use the os.walk method. Here is an example:

# !/usr/bin/pythonimport os
for root, dirs, files in os.walk(".", topdown=False):for name in files:print(os.path.join(root, name))for name in dirs:print(os.path.join(root, name))
