• 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 2,283 files with 147,628 lines of code.
• 2 very long files (2,433 lines of code)
• 16 long files (11,499 lines of code)
• 125 medium size files (35,857 lines of codeclsfd_ftr_w_mp_ins)
• 254 small files (35,779 lines of code)
• 1,886 very small files (62,060 lines of code)

There are 771 files with lines longer than 120 characters. In total, there are 1887 long lines.
