• 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 470 files with 42,723 lines of code.
• 1 very long files (2,151 lines of code)
• 10 long files (6,320 lines of code)
• 38 medium size files (11,543 lines of codeclsfd_ftr_w_mp_ins)
• 77 small files (10,732 lines of code)
• 344 very small files (11,977 lines of code)

There are 197 files with lines longer than 120 characters. In total, there are 976 long lines.
