• 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 7,027 files with 991,085 lines of code.
• 119 very long files (337,438 lines of code)
• 182 long files (123,030 lines of code)
• 710 medium size files (214,101 lines of codeclsfd_ftr_w_mp_ins)
• 1,148 small files (162,234 lines of code)
• 4,868 very small files (154,282 lines of code)

There are 3540 files with lines longer than 120 characters. In total, there are 33343 long lines.
