• 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 1,226 files with 383,332 lines of code.
• 102 very long files (201,601 lines of code)
• 89 long files (59,439 lines of code)
• 209 medium size files (65,619 lines of codeclsfd_ftr_w_mp_ins)
• 199 small files (28,815 lines of code)
• 627 very small files (27,858 lines of code)

There are 826 files with lines longer than 120 characters. In total, there are 36196 long lines.
