• 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 3,845 files with 296,608 lines of code.
• 21 very long files (74,792 lines of code)
• 28 long files (18,447 lines of code)
• 159 medium size files (45,286 lines of codeclsfd_ftr_w_mp_ins)
• 412 small files (56,597 lines of code)
• 3,225 very small files (101,486 lines of code)

There are 1228 files with lines longer than 120 characters. In total, there are 4441 long lines.
