Each logged-in user has a default custom dictionary accessible within PowerPoint and other Microsoft Office programs called RoamingCustom.dic. Additionally, you can create and use many more custom dictionaries. Over time, your custom dictionaries may become a very useful resource, especially since any custom dictionary loaded is used by all the Office applications such as Word, Excel, PowerPoint, and Outlook. Let us assume that you have added several words to the custom dictionaries over the last 4 or 5 years, and now you need to move to a new computer.
