• 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 409 files with 150,601 lines of code.
• 39 very long files (71,950 lines of code)
• 50 long files (34,345 lines of code)
• 83 medium size files (27,898 lines of codeclsfd_ftr_w_mp_ins)
• 63 small files (9,409 lines of code)
• 174 very small files (6,999 lines of code)

There are 64 files with lines longer than 120 characters. In total, there are 259 long lines.
