How regex? (I'm using Notepad++)

You can try like this: Search for [`.*\.\..*\n?`](https://regex101.com/r/hW0aZ1/1) and replace by empty. — bobble bubble, May 28 '16 at 12:00
Are the lines that you want to remove always follwoing the one without the dot? Would a check for 25 (or whatever number) equal characters at the start be suffivient? See [Regex101-Demo](https://regex101.com/r/lX2yP4/1) — Sebastian Proske, May 28 '16 at 12:01
@SebastianProske seems don't work `^(.{25,})(.*)$\n\1.*` I copy on notepad++ and select regular expression but it tell me **no matches** — Super Sonic, May 28 '16 at 12:44
@SuperSonic yep, better use `^(.{25,})(.*)$\R\1.*` for the search pattern (and still `$1$2` for replace) - does this work for you? — Sebastian Proske, May 28 '16 at 12:49
@SebastianProske Ok now it works - please write your answer so I can assign like solved. — Super Sonic, May 28 '16 at 13:56

To remove all lines that have 2 or more dots, I'll do:

Ctrl+H
Find what: ^.*\.\.+.*\R?
Replace with: NOTHING
Replace all

I think you can drop the `+`. Further this [won't strip the last line](https://regex101.com/r/cO6nG7/1) (if there is no `\n`). – bobble bubble May 29 '16 at 08:59

@bobblebubble: Good catch, I've made the line break optional. – Toto May 29 '16 at 10:23

Under the condition, that the line you want to remove always follows the line without the dots, you can use the following (make sure regular expression is checked in Notepad++ replace dialog):

Search pattern: ^(.{25,})(.*)$\R\1.*

Replace pattern: $1$2

This is checking for 25 characters in one line, that are repeated in the next line - and removes this second line. Of course you can replace 25 by whatever number you feel appropriate to avoid false positives.
