• 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 929 files with 96,975 lines of code.
• 10 very long files (14,455 lines of code)
• 21 long files (15,530 lines of code)
• 86 medium size files (24,595 lines of codeclsfd_ftr_w_mp_ins)
• 131 small files (18,256 lines of code)
• 681 very small files (24,139 lines of code)

There are 13 files with lines longer than 120 characters. In total, there are 84 long lines.
