How to use Config file diff?

After a game update, a mod change or edits by several admins, it helps to see exactly what changed in a config file. This tool compares two texts, line by line and key by key.

  1. Paste the old version in “File A” and the new one in “File B”.

  2. Read the key/value table: added, removed and changed keys.

  3. Check the line diff for ordering, comments and duplicates.

  4. Enable “Ignore whitespace” to hide indentation differences, then copy the summary.
