• 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 401 files with 47,265 lines of code.
• 6 very long files (8,092 lines of code)
• 13 long files (8,603 lines of code)
• 47 medium size files (13,994 lines of codeclsfd_ftr_w_mp_ins)
• 55 small files (7,638 lines of code)
• 280 very small files (8,938 lines of code)

There are 103 files with lines longer than 120 characters. In total, there are 659 long lines.
