maybe this is of help
open the desired file in notepad++
in the menu bar, click on view > show symbol > show all characters
(this will show you all line endings like [CR][LF])
then, if you select edit > eol (end of line) conversion > windows (CR LF) from the menu bar, it will convert all paragraphs (line endings) to the windows format (or mac or linux if you choose so)
