Great!!! I got the result in the output file, thank you so much!. But I need the output in Desending order by file size for individual month. The month date and file name should automatically match their file size as well, so I can find the largest file with its date and file name. I am not sure which code can handle it.

Here is the output:

File sizes are displayed in the second column. I am not sure what are the numbers following FILENAME, such as 38, 33 , 38 ....

Thank you for your wisdom, please enlighten me again!
