Original author BlueStyle hints for improvements
The old algorithm waited until the file was downloaded to calculate,
Now this is directly calculating the size when you get the file
Added fault tolerant statements
Added judge directory, no directory automatically created
Change the algorithm to calculate the file size
The previous one was just seven lines of code to calculate the file size,
Now this is just two rows
