• 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 253 files with 54,246 lines of code.
• 8 very long files (17,676 lines of code)
• 18 long files (12,601 lines of code)
• 40 medium size files (12,280 lines of codeclsfd_ftr_w_mp_ins)
• 46 small files (6,573 lines of code)
• 141 very small files (5,116 lines of code)

There are 145 files with lines longer than 120 characters. In total, there are 1861 long lines.
