Transfer Data Between Text Files

I have a collection of raw text files that hold structured data entries. Each source file follows the same simple pattern—one entry per line, fields separated by commas—and I need every entry moved into a new, consolidated text file while preserving the exact order and formatting.

You will open each source file, copy every line exactly as-is, and paste it into the destination file I provide. No re-typing or re-formatting is involved; accuracy is the only priority. A quick spot-check of the finished file must confirm that the total line count matches the sum of all sources and that every character—including line breaks and commas—remains unchanged.

Deliverable
• One final text file containing all data entries in sequence, ready for immediate use.

Acceptance criteria
• 100 % data fidelity (character-for-character match).
• Final file passes an automated diff check against the combined sources.

The task is straightforward but demands care and consistency, so attention to detail is essential.
