File association and opening methods in Windows 7

Because the work needs to analyze the source of a message, etc., because I am used to using Office Outook to view the mail attribute information, and the current system default mail program is Windows Live Mail, so use “ open method” Specifying the opening of the message by Office Outlook, but specifying the opening method because of negligence, did not remove the "always use the selected program to open this file" check results can be imagined.

And after this operation is executed, Office Outlook does not open the correct mail file (.eml type) correctly. Now it can only restore the previous state first, according to the experience of using Windows XP in the past. In the folder option, you can set the file key and open mode, but under Windows 7 gOxiA is confused! I haven't found it for a long time, because it is the reason of RC version, it is difficult to search related in the help system. Information, at least through several keywords can not be searched for related help. But I can be sure that the system will have a place to set up. This reminds me of the control panel —— system configuration center, after trying hard to find the location.

Open the control panel. By default, the control panel is arranged in categories, so as shown in the figure below, we need to click on “Program” to find the default program settings. Here we can change Specifies how the type file is opened and the default program settings.

Of course, under the category list arrangement, we may not be able to intuitively let us know the specific information of each setting function. I personally recommend switching the viewing mode to “large icon”, This way I can clearly understand the name of each setting function.

Click “Set Default Program", we can see the default program currently registered in the system in the program list box on the left side of the figure below, select Windows Live Mail, and click on the right & nbsp; Select the default value of this program & rdquo;, then in the "Setup Program Association" check the extension of the type of ".eml", click OK to complete the settings.

Of course, we can also specify the opening method of a specific file type by clicking on the file type or protocol associated with the program in the default program settings panel.
