Viewing File Extension Name

Sometime, you need to see your files extension. But many/almost all files are not viewing the extension anymore after it finds a program to open it. Maybe you knew it a long time ago, but I will tell you who doesn't know it yet. There only one setting needed to view the extension.

Follow these steps:
1) Open a folder or "My Computer"
2) Click "Tools" at menu bar (If I’m right), select "Folder Options"
Or
1) "Start Menu", "Control Panel"
2) "Switch to Classic view (For Win XP) at the left side", select “Folder Options"
3) Select "View" tab
4) At the "advanced Settings" un-check "Hide extension known file types"
5) OK

Now see your file names! There are the extension names.

NOTE: But BE CAREFUL, because now you can change the extension.
But if you changed/deleted the extension to other extension, IT CAN BE UNUSABLE!!
