I have generated some .dat files using Fortran on a cluster. I need to use WinSCP(https://winscp.net/eng/download.php) to access files in the cluster so sometimes I just use the WinSCP to open the .dat files generated. The data can be shown regularly like this one: https://www.dropbox.com/home/Pictures?preview=notepad2.jpg However, if I download it to my desktop and open it with notepad it becomes like this: https://www.dropbox.com/home/Pictures?preview=notepad1.jpg It bothers me because usually I read the file in PC and I need to share it to some other people and I don't expect they open it in WinSCP. How can I change the format so it looks better? Thank you.
