Settings file created and used by TestComplete, an application that allows users to test web, desktop, and mobile programs; stores project settings that are common for testers, such as the names of project items and the scripting language.

More Information

One of the main features of a TestComplete project and project suite is to let you and others test different applications using the same settings. A MDS file holds the settings that allow you to do this. The file is similar to a .PJS file but holds information for just one project instead of a suite of projects.
