• File size measurements show the distribution of size of files.
• Files are classified in four categories based on their size (lines of code): 1-100 (very small files), 101-200 (small files), 201-500 (medium size files), 501-1000 (long files), 1001+(very long files).
• It is a good practice to keep files small. Long files may become "bloaters", code that have increased to such gargantuan proportions that they are hard to work with.

• There are 96 files with 28,929 lines of code.
• 8 very long files (12,703 lines of code)
• 7 long files (4,317 lines of code)
• 28 medium size files (8,697 lines of codeclsfd_ftr_w_mp_ins)
• 11 small files (1,631 lines of code)
• 42 very small files (1,581 lines of code)

There is only one file with lines longer than 120 characters. In total, there is only one long line.
