Microsof Project plan

[Jason-W]

Hi,

Yes, you will need MS Project to open the file. I believe
the Standard edition can be purchased online (There is
also a free demo)

Or you can request the person who sent you the file to
send it as one of the viewable formats per this faq:

See item #16: Project Viewer.

HTH,
