You may feel scared of your monster PowerPoint Deck contains 30 PowerPoint slides. Now you have tools for handling the large presentation. You can get two ways for managing and modifying the presentation on the move. Now you need not to take tension anymore about your large and extra-large presentations with these tools. Like while using large number of files you have to scroll and navigate slides that take a lot of time. Analyzing the presentation into logical segments, you will gain the All Section tool in office 2010 and 2013 that gives you the cleaner visual of your presentation and you will be able to arrange the slides in an easy way.
Another way is custom slide shows. You must have seen that there are some large decks that are not meant to be viewed all in a row in one presentation. You need to select all slides from the master deck and create a smaller subset. Therefore, one of the great solutions of this scenario is custom slide show. With the help of this custom slide show, one can create multiple configurations of one single presentation file. You will get the configuration stored with your PPT file and that will be made available from the custom slide show button.
