Microsoft Project is Project Management Software.
Project files starting with Project version 4, are in the "OLE2" document container format. Project files do not appear to have moved to the later XML format like other Microsoft Formats and remain as OLE containers.
The format appears to remain the same since Project 2010, and newer saved formats can be opened in the older versions.
An MPX or Microsoft Project Exchange file format (ASCII) can be exported for exchanging data with other PM software.
