Changing the default directory in which emacs save the files

[Carlos Gomes]

Dear Sir or Madam,

I am a big fan and a GNU Emacs user and although I have several books about it, I have not found the answer for one specific question in any of them. I have GNU Emacs installed in my computer on both windows and linux operative systems, and I have been looking for a way that allows me to change the directory in which emacs saves the files that I am working with. That is, is there a way to "tell" emacs to save a file in a directory other than, for instance, C:\Programs\emacs\bin (the default) in windows, by using the command C-x C-s (save-buffer)?

Thank you very much for your time.

I am looking forward to hearing from you.

Sincerely,

Carlos Gomes
