• 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 40,533 files with 2,830,701 lines of code.
• 127 very long files (224,740 lines of code)
• 376 long files (252,482 lines of code)
• 2,246 medium size files (665,891 lines of codeclsfd_ftr_w_mp_ins)
• 4,516 small files (626,781 lines of code)
• 33,268 very small files (1,060,807 lines of code)

There are 5879 files with lines longer than 120 characters. In total, there are 21910 long lines.
