you can understand in this way:
The file name here is where you save your work. 
( you use close() to save your file )
So it doesn't matter the file has data inside or not. 
ONLY the data in the handle will write to your file.
ie. This ">" is an overwrite, if you are opening an existed file

So, since you are open a file for WRITE, so it couldn't READ, while you read
nothing, so you write nothing. End up, you harvest an empty file
