I can't find anywhere this function..if I have a duplicate, I want to delete it for all.
Ex:
Original file

Code:

A
B
B
C

So, B and B are duplicates. I want to delete BOTH lines, to get a result like:

Code:

A
C

BigTroll, get Notepad++ its free, and use its find and replace feature to delete duplicate lines.

Think you should heed Brad100 advice. Think this would be the most feasible method.

Thanks, but I can't find this option. I don't want to delete duplicate lines only to keep only 1 original, I want to delete both. Like on my example, if I have 4 lines:
A
B
B
C

After this operation, I need to keep only 2 lines:
A
C
