How does case sensitivity work?
When case sensitive is enabled, 'Apple' and 'apple' are treated as different lines. When disabled, they're considered duplicates.
What does trim whitespace do?
Trim whitespace removes spaces and tabs from the beginning and end of each line before comparing for duplicates.
Can I process large text files?
Yes, the tool can handle large amounts of text. For very large files (over 100MB), consider using desktop tools for better performance.
