Delete every other line in notepad++

Question

Is there a way in Notepad++ to delete every other or nth line? I have a massive list of data and I need to reduce the size.

The data itself is not that important an

Answer 1

I don't think there is a feature in Notepad++ that will automatically delete every other (or every nth) line, but if you wrote a short conversion program it would only take a few minutes.

The pseudocode would look something like this:

1. Create a StreamReader and StreamWriter (make sure you are not trying to read from
   and write to the same file)
2. While (StreamReader is reading lines) increment i. You could mod it by whatever 
   number n you wanted in order to delete certain lines. Then have a conditional clause
   that would write out if i%n == 0 or whatever you specify.
3. Close the program.

That doesn't exactly answer your question, but I hope it helps.
