Plan for Windows

Plan is a project planner which is similar to, and compatible with, Microsoft Project.

Plan for Windows can be used in various ways:

As a viewer for Microsoft Project files - it can directly read and write Microsoft Project files (MPP/MPD/MPX can be read, MPD/MPX can be written).

As an inexpensive alternative to Microsoft Project. Plan doesn't have all the bells and whistles of Microsoft Project, but this makes it much easier to use. This makes it a highly cost effective alternative to Microsoft Project.
As a stand-alone project planning tool - it is a fully functional project estimation tool. It supports creation and editing of project plans, including recalculation of a project schedule.
Use in conjunction with Pocket Plan on a Pocket PC or Handheld PC. This allows you to access and update your project plans anywhere - at your desktop or in a meeting or anywhere else via your Pocket PC.
