• 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 450 files with 69,094 lines of code.
• 10 very long files (20,490 lines of code)
• 19 long files (13,036 lines of code)
• 56 medium size files (17,128 lines of codeclsfd_ftr_w_mp_ins)
• 54 small files (7,250 lines of code)
• 311 very small files (11,190 lines of code)

There are 77 files with lines longer than 120 characters. In total, there are 243 long lines.
