>>>     difference = [1,2] - here why you took size 2 of array?
So that a variable called difference exists for the next line, and is 
not 1.
>>>     until difference.size == 1 - why 1?
Because then there will be a single file, which is the one you've just 
downloaded. More than one is venturing into the unknown :)
>>>       difference = Dir.entries(@download_directory) - @current_downloads
>>>in the above line what are we doing?
The current files minus the previous files = the new file.
