What is a 50MB TXT file useful for?
A 50 MB TXT file with ~750,000 lines is an infrastructure limit-testing file for text processing pipelines. No typical web app upload form expects users to submit a 50 MB plain-text file — use it to verify that your upload endpoint enforces a size limit before processing, that the rejection is fast, and that streaming text processing (line-by-line) handles this size within memory limits when it is within your supported range.
What's inside this file?
Generated by data.py. Approximately 750,000 lines of lorem ipsum body text with paragraphs and '##' headings. Reading this file via Python's lazy file iterator uses approximately 1–5 MB of RAM (one line at a time). Loading with open().read() uses approximately 50 MB of RAM (one large string). Full in-memory line split (splitlines()) uses approximately 200 MB due to Python list and string object overhead.
