What is a .ADT file?

An ADT file is a special kind of file that works with ACT!, a program used for managing contacts and other information. Think of an ADT file like a blank form letter that you can fill out multiple times with different information, but the basic layout stays the same each time. This is really helpful when you need to create a lot of documents that look similar but have different details.

To open an ADT file, you would use a program called Swiftpage Act!. This program knows how to read the ADT file and help you create new documents using the template.

There's also something interesting about ADT files related to video games, specifically a game called World of Warcraft (WoW). In this context, ADT files are packed into something called .MPQ archives. These archives are like big containers that hold all sorts of game data, including updates and changes to the game world. So, when WoW gets updated, it might include ADT files that change parts of the game's map, like adding new areas or altering existing ones. Examples of these game-related ADT files have names like Northrend_33_18.adt, Azeroth_29_47.adt, and IcecrownCitadel_25_28.adt, which refer to different locations within the game.
