About files with "~" at the ends of them or "#" on both sides in Unix

The Emacs text editor creates these files when it performs backups and autosaves of your files. Whenever you start Emacs to edit a file, Emacs creates a backup with the same name, but with a ~ (tilde) tacked on to the end. Emacs creates the files that begin and end with a # (pound sign) when it executes an autosave. Normally, Emacs deletes the autosave when you exit; however, if Emacs crashes or its process is killed, then these files remain.

If you want to keep backups for your important files, then it's not a bad idea to keep these files around. However, if you delete them, under normal circumstances, you won't lose any information.
