• 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 4,262 files with 802,367 lines of code.
• 180 very long files (371,886 lines of code)
• 216 long files (149,110 lines of code)
• 413 medium size files (129,262 lines of codeclsfd_ftr_w_mp_ins)
• 500 small files (71,424 lines of code)
• 2,953 very small files (80,685 lines of code)

There are 339 files with lines longer than 120 characters. In total, there are 1854 long lines.
