If you close a file after you've made changes, without saving it first, WordPerfect will ask you if you want to save the changes. There are a couple of ways to do this. Sometimes you might want to keep several files open at the same time. Exercise 15 Close any documents you have open. Close all the open documents.
Preview slows down the process of opening files, so use it with discretion.
Close the files that are open. WordPerfect will let you know that the file is already being used. You can still open it, but will only be able to save any editing changes if you change the file name. Add some words to the document and then click on FILE and Save . WordPerfect will only let you save this file if you give it a different file name.
