• 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 1,756 files with 213,627 lines of code.
• 26 very long files (48,191 lines of code)
• 40 long files (26,231 lines of code)
• 177 medium size files (56,598 lines of codeclsfd_ftr_w_mp_ins)
• 264 small files (37,170 lines of code)
• 1,249 very small files (45,437 lines of code)

There are 17 files with lines longer than 120 characters. In total, there are 185 long lines.
