What is an .ADT file?

.ADT is ACT! Document Template

An ADT file is a template for creating a new word processing document in ACT! contact management software. It is used for creating multiple documents with a similar layout.

ADT files may be created with a third-party word processor, such as Microsoft Word, which works in conjunction with ACT!. The default location for storing ADT files is "C:\Program Files\ACT\Templates."

NOTE: Sage ACT! became Swiftpage Act! in 2013.
