Hi,
How i can store backup files (which are created by
emacs) in one particular directory?
If possible please send me .emacs code too.

Thanks,

Dealing with emacs backup files is explained in the subsection
*Backup* within the *Saving files* section of the Emacs
Manual. Here is a quotation:

   "you can customize the variable `backup-directory-alist' to
   specify that files matching certain patterns should be
   backed up in specific directories".

     "A typical use is to add an element `("." . DIR)' to make
   all backups in the directory with absolute name DIR; Emacs
   modifies the backup file names to avoid clashes between
   files with the same names originating in different
   directories.  Alternatively, adding, say, `("." . ".~")'
   would make backups in the invisible subdirectory `.~' of
   the original file's directory.  Emacs creates the
   directory, if necessary, to make the backup."

The following is a snippet of my .emacs. You must read the
*Backup* subsection in order to adapt it for you.

;; ------------------ Setting the handling of backups -------------------
(setq backup-directory-alist
      '((".+\\.tex$" . "~/backup/tex")
        ("/[^\\./]+\\..+$" . "~/backup/code")
        ("/[^\\.]+$" . "~/backup")
        ("/\\.." . "~/backup/dotfiles")))
;; backup variables
(setq
 version-control t
 kept-new-versions 6
 kept-old-versions 6
)
;; ---------------------- End handling of backups------------------------
