JetBrains / leveldb File Size

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

2 very long files (2,473 lines of code)
4 long files (2,724 lines of code)
14 medium size files (4,198 lines of codeclsfd_ftr_w_mp_ins)
15 small files (2,152 lines of code)
69 very small files (2,773 lines of code)
