Use C-x C-f to visit a file. If the file does not exist yet, Emacs creates the buffer first and writes the file when you save.

• Visit a file with Visiting Files.
• Save the current buffer with Saving Files.
• Save a buffer under a new name with Saving Files.
• Recover interrupted work with Reverting a Buffer and Auto-Save Files.
• Rename, copy, and delete files with Miscellaneous File Operations.

The main file commands are also listed in the Command and Function Index.
