• 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 439 files with 79,480 lines of code.
• 15 very long files (44,398 lines of code)
• 13 long files (8,676 lines of code)
• 34 medium size files (9,700 lines of codeclsfd_ftr_w_mp_ins)
• 44 small files (6,377 lines of code)
• 333 very small files (10,329 lines of code)

There are 164 files with lines longer than 120 characters. In total, there are 1546 long lines.
