• 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 418 files with 46,932 lines of code.
• 2 very long files (3,405 lines of code)
• 6 long files (4,335 lines of code)
• 55 medium size files (16,632 lines of codeclsfd_ftr_w_mp_ins)
• 84 small files (11,741 lines of code)
• 271 very small files (10,819 lines of code)

There are 7 files with lines longer than 120 characters. In total, there are 15 long lines.
