Large Files That Change Often (Top 9)
To change a file, an AI coding agent (or a person) has to read it: these files are read the most for the changes in the past year (lines × changes).
| File | # lines | ≈ tokens to read | # changes (1y) | ≈ lines edited per change | lines read per line changed |
|---|---|---|---|---|---|
| 545 | ~3k–10k | 1 | ~20 | ~20 | |
| 545 | ~3k–10k | 1 | ~700 | ~1 | |
| 493 | ~3k–7k | 1 | ~50 | ~10 | |
| 493 | ~3k–7k | 1 | ~700 | ~1 | |
| 274 | ~1.5k–5k | 1 | ~50 | ~5 | |
| 274 | ~1.5k–5k | 1 | ~300 | ~1 | |
| 65 | ~300–1k | 1 | ~10 | ~5 | |
| 65 | ~300–1k | 1 | ~100 | ~1 | |
| 55 | ~300–1k | 1 | ~100 | ~1 |
Tokens are lines × 7 to 14 (analysis.fileReadsForChanges). Lines edited per change are the file's lines added and deleted divided by its commits over the whole history. Agents read about 2,000 lines at a time: when a 17,000-line file was split into modules, the tokens an agent read for the same change fell by 83% (The Economic Benefit of Refactoring, 2026).

About This Analysis
- 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.
