vim - Is write / Save / :w the same in gVim -

in gvim have following file menu:

next save says :w.

recently i've been informed :w not save write.

why menu set out , differences between write / save / :w ?

"save" standard term "write disk", , that's plain :w does.

however, :w has number of additional arguments can make other things, such append part of current file other file (see :h :w). hence, more accurate call :w write command, rather save command - plain :w equivalent simple save command.
