Frequently asked questions
Which copy of a duplicate is kept?
The first one, in its original position. Lines are compared after trimming spaces at their ends.
How do I sort lines alphabetically?
Choose A–Z or Z–A. Sorting is natural and locale-aware: item2 comes before item10, and accented letters sort next to their base letter (c, ç, d).
Can I keep empty lines?
Yes. Turn off “Remove empty lines”.
