• 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 137 files with 27,586 lines of code.
• 5 very long files (7,227 lines of code)
• 7 long files (4,577 lines of code)
• 31 medium size files (8,842 lines of codeclsfd_ftr_w_mp_ins)
• 26 small files (3,726 lines of code)
• 68 very small files (3,214 lines of code)

There are 25 files with lines longer than 120 characters. In total, there are 129 long lines.
