• 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 22,067 files with 4,985,691 lines of code.
• 889 very long files (2,323,493 lines of code)
• 1,216 long files (859,219 lines of code)
• 2,892 medium size files (905,331 lines of codeclsfd_ftr_w_mp_ins)
• 3,026 small files (432,975 lines of code)
• 14,044 very small files (464,673 lines of code)

There are 3556 files with lines longer than 120 characters. In total, there are 26481 long lines.
