How can i open a .map file and view it....

[waldronate]

You'll need to provide a little more context because there are map file types with the extension ".map". A pointer to the file in question might help, if possible.

[johnvanvliet]

as above some more information is needed

Things like

What software created it ? ( if known )

Where did you find this "*.map" file ?
a link to the website WILL HELP

[Gidde]

A .map file is not actually a map. It's a file that holds code for an imagemap on a webpage (i.e. when you click different places on the image it goes to different links).

[waldronate]

There are many different kinds of .map files (for example, linker map files, color map files, heightfield data files all can share the .map extension). Without a context, it's impossible to know what this request might be referring to.
