• 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 423 files with 87,718 lines of code.
• 10 very long files (22,436 lines of code)
• 27 long files (17,785 lines of code)
• 85 medium size files (25,750 lines of codeclsfd_ftr_w_mp_ins)
• 79 small files (11,913 lines of code)
• 222 very small files (9,834 lines of code)

There are 329 files with lines longer than 120 characters. In total, there are 5166 long lines.
