• 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 450 files with 35,628 lines of code.
• 5 very long files (10,469 lines of code)
• 3 long files (1,669 lines of code)
• 16 medium size files (5,331 lines of codeclsfd_ftr_w_mp_ins)
• 33 small files (4,572 lines of code)
• 393 very small files (13,587 lines of code)

There are 49 files with lines longer than 120 characters. In total, there are 676 long lines.
