Files with .mpt extension are Microsoft Project template files. These contain basic information and structure along with document settings for creating .MPP files.
MPX, Microsoft Exchange File Format, is an ASCII file format for transferring of project information between Microsoft Project (MSP) and other applications that support the MPX file format such as Primavera Project Planner, Sciforma and Timerline Precision Estimating. The MPX file format allows you to transfer project information that cannot appear in a table, such as detailed resource assignment information, calendar information, or information in the Project Info dialog box.
