• 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 7,566 files with 771,048 lines of code.
• 44 very long files (89,002 lines of code)
• 142 long files (95,077 lines of code)
• 618 medium size files (183,988 lines of codeclsfd_ftr_w_mp_ins)
• 1,171 small files (164,571 lines of code)
• 5,591 very small files (238,410 lines of code)

There are 179 files with lines longer than 120 characters. In total, there are 828 long lines.
