• 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 143 files with 33,666 lines of code.
• 4 very long files (13,311 lines of code)
• 10 long files (6,721 lines of code)
• 21 medium size files (6,568 lines of codeclsfd_ftr_w_mp_ins)
• 25 small files (3,437 lines of code)
• 83 very small files (3,629 lines of code)

There are 78 files with lines longer than 120 characters. In total, there are 509 long lines.
