• 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 2,946 files with 276,005 lines of code.
• 20 very long files (29,547 lines of code)
• 46 long files (31,507 lines of code)
• 269 medium size files (82,502 lines of codeclsfd_ftr_w_mp_ins)
• 399 small files (55,973 lines of code)
• 2,212 very small files (76,476 lines of code)

There are 885 files with lines longer than 120 characters. In total, there are 3473 long lines.
