• 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 1,344 files with 121,672 lines of code.
• 12 very long files (20,578 lines of code)
• 26 long files (16,381 lines of code)
• 95 medium size files (28,945 lines of codeclsfd_ftr_w_mp_ins)
• 153 small files (20,544 lines of code)
• 1,058 very small files (35,224 lines of code)

There are 96 files with lines longer than 120 characters. In total, there are 379 long lines.
