Every wonder what file extension is associated with what program in Windows? Need to know what program is associated with what file extension? Let me tell you how!

So what exactly is a file extension? A file extension is the last characters after the period in the name of a file. If you currently don’t see them in Windows Explorer, you can enable this very easily.

– Select Tools Then Folder Options in Windows Explorer
– Select the View Tab
– Scroll down to the entry that says “Hide file extensions for known file types” and make certain it’s not checked.
– Click on the Apply To All Folders button and then close the window.
