Why do some .Net exceptions end with a newline

I have a ListView that shows an error to the user. Part of it also includes an exception message. The error is also written to the log file.

Now I noticed that some exception messages end with a new line. for example, File.Move may return a message (English .Net 3.5 SP1) "Unable to create file if this file already exists. \ R \ n" .

A new line makes listview and logfiles look weird. Adding .Trim () fixes the problem, but there is a reason for the new line.
