@Coises funzt. Danke

Hello, @dougk.az and All, I suppose that using this simple regex replacement, below, should work ! Open your text in N++ Move back at the very beginning of your file Open the Replace dialog ( Ctrl + H ) Uncheck all box options FIND \r\n? REPLACE Leave EMPTY Check the Wrap around option Select the Regular expression search mode Click, once, on the Replace All button Here you are ! To verify that all your lines are just concatenated, without any char in between, simply use the ¶ icon of the Toolbar. All the LF characters are preserved ! Best Regards, guy038

@vvPeterJones I switched Settings>Preferences>Print from “No background color” to “Black on white” and the print is much better.

Even if the shorter, similar string was after the longer string, the same Regular Expression (Regex) can be used to get the same result:- Input abcdefghijklmnopqrstuvwx abc Output abcdefghijklmnopqrstuvwx ABC Explanation: The abc.*xyz preceding the (SKIP)(*F) in the Regex helps skip the long string starting with abc and ending with xyz and matches the other abc in the shorter, similar string! By using that Regex (mentioned in my previous post, just above this), the abc after the (SKIP)(*F) is matched, found and replaced.
