When to use C-X C-C in Emacs?
C-x C-c, the key sequence to exit Emacs, invokes save-some-buffers and therefore asks the same questions. If you have changed a buffer but do not wish to save the changes, you should take some action to prevent it. Otherwise, each time you use C-x s or C-x C-c, you are liable to save this buffer by mistake.
Are there any commands to save files in Emacs?
With a prefix argument, C-u C-x C-s, Emacs also marks the buffer to be backed up when the next save is done. See Backup . The command C-x s ( save-some-buffers) offers to save any or all modified buffers. It asks you what to do with each buffer. The possible responses are analogous to those of query-replace :
What does set visited file name do in Emacs?
It reads the new file name using the minibuffer. Then it marks the buffer as visiting that file name, and changes the buffer name correspondingly. set-visited-file-name does not save the buffer in the newly visited file; it just alters the records inside Emacs in case you do save later.
How is a GnuPG file treated in Emacs?
The variable auto-mode-alist controls how Emacs assigns major modes when you open certain files; in this instance, any file that ends with .gpg is treated as a GnuPG file in Emacs. To test it out, open a file – such as /tmp/foobar.gpg – write some text and then save it with C-x C-s.

What does C-X C-S do after saving a file?
After saving is finished, C-x C-s displays a message like this: If the current buffer is not modified (no changes have been made in it since the buffer was created or last saved), saving is not really done, because it would have no effect. Instead, C-x C-s displays a message like this in the echo area:
