notepad++ adding extra lines to a file

I've been bugged with this problem for ages and I just tried to ignore it, but when I open files for the first time that was saved from a mac/unix box, I get to see an extra line break after each line:

something like

this

which is pretty

annoying

What I usually do is just do one of the many fixes for this behavior in google, like the TextFX solution to delete all blank lines.

But I am just curious as to why this happens. Why? Why does it not happen again even if I save the file, push it to the git repo(and when it gets edited by another user in a mac/unix) I don't get this problem anymore?

EDIT

the git problem was a problem I had before but our current problem right now is that we are uploading files using rail's paperclip, which saves it to the file system(we are using a windows machine). when we open the files, we see it as "macintosh" "ansi" even if the server is running on windows. is there a way to make it open it with the proper encoding by default?

Solution 1:

I've been struggling with the same issue for several years, but after reading this post and trying some settings in Notepad++ it didn't appear to be Notepad++ that's changing the LF or CR settings.

My 'problem' was caused by a Filezilla setting, with which I download the files from my website to edit them in Notepad++.

In Filezilla I had a lot of extensions in the setting 'Automatic file type classification' (go to Edit > Settings > Transfers > File types). After I cleared them all and re-downloaded my file it opened just fine in Notepad++, no more extra line breaks. Also tested to edit the file, upload it, download and edit it again.

So, in Notepad++ my default setting for new files is:

• Encoding: ANSI
• Format: Windows

And in Filezilla the settings are:

• Transfer type: Auto
• Automatic file type classifications: extensions list is empty

This solved my problem.

Hope it helps.

Solution 2:

I tried the above solutions and none were working for me, but it did turn out that it was FileZilla though.

I found a recommendation in one of their forums to transfer using binary mode instead of auto. Once I changed this, my problem was solved. :)

Exerpt:

Set Transfer type (menu Transfer) from Auto to Binary and upload your script.
