what is .org~ ?

I just started learning emacs, especially org mode. When I edit .org files and save it, .org\~ is created in the same directory and I am not sure what this file is. I can't find any info about it. What is the point of .org\~ file? I think it is the original file but what can I do so that .org\~ files aren't created

Those are backup files. https://www.gnu.org/software/emacs/manual/html_node/elisp/Backup-Files.html I generally create a backup directory and dump the files in there in case I need them. I’ve never actually needed them but space is cheap.

See https://www.gnu.org/software/emacs/manual/html_node/emacs/Backup.html

You can set the backup and auto-save directory to /tmp/ pretty easily: ```elisp ;; Store all backup and autosave files in the tmp dir (setq backup-directory-alist `((".*" . ,temporary-file-directory))) (setq auto-save-file-name-transforms `((".*" ,temporary-file-directory t))) ```
