• 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 510 files with 68,903 lines of code.
• 5 very long files (12,863 lines of code)
• 13 long files (8,760 lines of code)
• 65 medium size files (20,496 lines of codeclsfd_ftr_w_mp_ins)
• 94 small files (13,181 lines of code)
• 333 very small files (13,603 lines of code)

There are 197 files with lines longer than 120 characters. In total, there are 869 long lines.
