• 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 1,280 files with 210,997 lines of code.
• 26 very long files (48,439 lines of code)
• 51 long files (33,265 lines of code)
• 202 medium size files (62,888 lines of codeclsfd_ftr_w_mp_ins)
• 237 small files (34,103 lines of code)
• 764 very small files (32,302 lines of code)

There are 307 files with lines longer than 120 characters. In total, there are 1774 long lines.
