• 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 1,108 files with 241,442 lines of code.
• 52 very long files (124,357 lines of code)
• 49 long files (34,392 lines of code)
• 131 medium size files (41,123 lines of codeclsfd_ftr_w_mp_ins)
• 137 small files (19,671 lines of code)
• 739 very small files (21,899 lines of code)

There are 92 files with lines longer than 120 characters. In total, there are 541 long lines.
