• 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 39 files with 10,501 lines of code.
• 2 very long files (4,385 lines of code)
• 3 long files (2,259 lines of code)
• 5 medium size files (1,479 lines of codeclsfd_ftr_w_mp_ins)
• 11 small files (1,601 lines of code)
• 18 very small files (777 lines of code)

There is only one file with lines longer than 120 characters. In total, there are 2 long lines.
