All Of Text Files Are Showing With Par In Them

I use the Commandline with just about everything I do on my laptop, often utilizing batch scripts that I've written, from editing, renaming, moving, timestamping, exif manipulation of my image files to SET-ting variables etc..

There remains quite a bit of internal commands that I'm not familiar with. One of them being the "sort" command of which I think may be responsible for my current issue.

I read a little about it via the "/?" command then gave it a little input until it occurred to me from the returns that command was supplying of which were no returns at all, that I was not doing things right so I got bored and went onto something else. It seems that since that time, all my text files have had "par" appended to them. and I don't know how to correct this.

At one point It looked like this would only happen if I opened them from the command prompt but then noticed "par" was there if I double clicked the text file. Is this something to do with that "Sort" command or is it something else all together? And, how in the heck can I fix it because it's really getting on my nerves as I'm creating some Tutorials pages utilizing "Choice" and "More" with cmd.exe being the viewer and every time I format some text, get it all prettied up for the tut program command muffles it up with that damn "par"!
