• 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 134 files with 23,480 lines of code.
• 3 very long files (9,044 lines of code)
• 4 long files (3,065 lines of code)
• 16 medium size files (4,683 lines of codeclsfd_ftr_w_mp_ins)
• 18 small files (2,752 lines of code)
• 93 very small files (3,936 lines of code)

There are 48 files with lines longer than 120 characters. In total, there are 402 long lines.
