suo file, what is this ?:

NO, do not add it to your CM system.

The .suo files contain user dependant information, like the state of the solution explorer (collaps all nodes, close the solution, delete the file and you'll notice that the nodes in the solution explorer are expanded again).

 More than that, if you keep your files in your Document's folder on Windows, it's got your login name in it as well.  /sigh
