10MaxSizeFiles.py

'''
Create a program/script in any language like Python, Bash, C, C++ etc. The program should scan all the Drives and folders like C:/User/* (Windows) and /home/* (Linux) recursively and then identify the top 10 files which have the largest size on the system.

Example: The tool should scan the Downloads folder, Documents Folder, Movies folder, C drive, E drive etc and display the 10 biggest files in these folders with their size in MB.
