Frequently Asked Questions
What does 'case-sensitive' mean?
If 'case-sensitive' is checked, the utility will treat uppercase and lowercase letters as different. For example, 'Dog' and 'dog' would both be kept as unique entries. If unchecked, they would be considered duplicates, and only the first one encountered would be kept.
Does this utility sort the list?
No, this tool preserves the order of the original list. The first occurrence of each unique line is kept in its original position.
