• 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 829 files with 140,870 lines of code.
• 20 very long files (35,492 lines of code)
• 49 long files (34,901 lines of code)
• 105 medium size files (33,936 lines of codeclsfd_ftr_w_mp_ins)
• 128 small files (18,052 lines of code)
• 527 very small files (18,489 lines of code)

There are 80 files with lines longer than 120 characters. In total, there are 256 long lines.
