Go to help and type "file association"
Change the program that opens a type of file
If you double-click a file in Windows and it opens in the wrong software
program, follow these steps to choose the program you would prefer that file
use. You can change this setting for an individual file, or you can tell
Windows to open all files of that same type in the software program you
choose.
1.. Open the folder that contains the file you want to change.
2.. Right-click the file that you want to change, and then, depending on
the type of file, either click Open With or point to Open With and then
click Choose Default Program.
3.. Click the program that you want to use to open this file.
4.. Do one of the following:
a.. If you want all files of that type to open in the same software
program, select the Always use the selected program to open this kind of
file check box, and then click OK.
b.. If you want only that file to open in the software program this one
time, clear the Always use the selected program to open this kind of file
check box, and then click OK.
