Frequently asked questions

Does it keep the original order?

The first occurrence of each line is kept, in its original position.

Is the comparison case-sensitive?

Check the option on the tool. If it is case-sensitive, Apple and apple count as different lines.

What about extra spaces?

Lines that differ only by trailing spaces may be treated as different, so trim them first if needed.
