QUESTIONS
Frequently asked questions
Which copy of a duplicate is kept?
The first one. Later repeats are removed, and the original order stays unless you pick a sort option.
What does “Ignore case” do?
It treats “Apple” and “apple” as the same line. The first spelling is kept.
How is natural sorting different from A to Z?
Natural sorting orders numbers the way people expect: item 2 comes before item 10. Plain A to Z puts item 10 first because it compares character by character.
