• 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 604 files with 232,353 lines of code.
• 65 very long files (115,763 lines of code)
• 77 long files (56,720 lines of code)
• 118 medium size files (38,663 lines of codeclsfd_ftr_w_mp_ins)
• 80 small files (11,538 lines of code)
• 264 very small files (9,669 lines of code)

There are 55 files with lines longer than 120 characters. In total, there are 134 long lines.
