• 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 4,400 files with 291,147 lines of code.
• 13 very long files (17,513 lines of code)
• 39 long files (26,041 lines of code)
• 223 medium size files (68,202 lines of codeclsfd_ftr_w_mp_ins)
• 485 small files (68,588 lines of code)
• 3,640 very small files (110,803 lines of code)

There are 1684 files with lines longer than 120 characters. In total, there are 6904 long lines.
