• 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 552 files with 69,200 lines of code.
• 13 very long files (21,579 lines of code)
• 15 long files (10,787 lines of code)
• 40 medium size files (13,018 lines of codeclsfd_ftr_w_mp_ins)
• 72 small files (10,035 lines of code)
• 412 very small files (13,781 lines of code)

There are 300 files with lines longer than 120 characters. In total, there are 3609 long lines.
