Each logged-in user has a default custom dictionary called RoamingCustom.dic — in addition 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. Or probably you have a colleague who is going to help you with some documentation, and you obviously want him or her to use your custom dictionary. To share the actual dictionary files (.dic), you first need to find out where they are stored on your computer.
