What is an MDS file?

An MDS file is an information file that describes the formatting of a CD or DVD. It includes header information, which defines the tracks on the disc and the way the data is organized. MDS files are recorded by disc imaging programs and recognized by standard CD and DVD players.

More Information

The MDS file is often found with a corresponding .ISO file or .MDF file, which contains the actual data from the disc. It is similar to a .CUE file, which describes the data stored in a .BIN file.

What is an MDS file?

An MDS file contains settings created and used by TestComplete, an application that allows users to test web, desktop, and mobile programs. It 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. An 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.
