The distribution of size of files (measured in lines of code).

Intro

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.

File Size Overall

There are 543 files with 323,799 lines of code.

92 very long files (203,074 lines of code)
88 long files (61,378 lines of code)
118 medium size files (38,714 lines of codeclsfd_ftr_w_mp_ins)
92 small files (13,728 lines of code)
153 very small files (6,905 lines of code)
