Answer 14 May 2013   license: CPOL
There is no direct way for removing a line from a file. However you might read the input file line by line, copying to a new file only the lines you want to maintain. At the end of the process discard the original file and rename the freshly written one.

On Windows system newline is "\r\n" (see, for instance Wikipedia[^]). Hence it should work (you should see proper output on notepad, other applications are able to render text file with other newline conventions).Please check (with the help of an hex editor) the actual file content.
