• 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 649 files with 183,758 lines of code.
• 32 very long files (87,982 lines of code)
• 54 long files (38,469 lines of code)
• 103 medium size files (32,289 lines of codeclsfd_ftr_w_mp_ins)
• 91 small files (12,948 lines of code)
• 369 very small files (12,070 lines of code)

There are 164 files with lines longer than 120 characters. In total, there are 1359 long lines.
