------------------------------------
Description:
Consider the scenario where we have two folders source and destination both
have file with SAME NAME use copyFrom method file will be copied (replaced) in
the destination folder alright but size of the file WILL NOT BE UPDATED IF THE
SIZE OF DESTINATION FILE BEFORE COPY WAS GREATER THAN THE SIZE OF SOURCE FILE.
In order to produce this issue. Use following code. and also take 2 image files
in two different folders. Also make sure the destination folder contains image
with higher size.
