Free MS Project Viewer : MOOS

The new buzz in the corporate world is “Projectization”.
That means you will receive more and more project plans in the most widely used format “MS-Project”. As MS-Project is not a part of Routine MS Office, You would need a project viewer to view contents. Unfortunately, Microsoft does not offer a free MS Project viewer.
You need an alternative that can show the contents of MS-Project formats like. mpp, . mpx etc.

Here is one such free tool to view the files. The lite version can be downloaded from here or you can view the contents in a free online viewer web browser. You can download it from its Website here
