What is the example for save and save as?
When you click on "Save" for a new document, you are asked the
same question as "Save as" -- that is, choose a title and format to
save it as. If, however, you are working on a previously saved
document and wish to merely save changes you've made, click on
"Save." If, however, you wish to save it as a different title or
format, click on "Save as." This way you will end up with two
versions, the old and new ones. For example, if you have an MS Word
document (.doc) and wish to also save it as a Wordpad document
(.rtf), click on "Save as" and change its format in the drop-down
menu. You may get a notice that the new format may not show the
document exactly as it is in the original format; so be sure to
look it over and make any necessary adjustments.
