To change the file association for a extension go to Windows Explorer or My Computer, go to
Tools
,
Folder Options,
then click on the
File Types
tab. In the list below you will see almost every type of file extension you will encounter. After highlighting the desired extension, you can click the change button below, and browse to the program you want those files to be opened with. Aside from graphics files, a common extension people want to change is a .MP3 file. For example, you may want your MP3 files to be opened with iTunes rather than Windows Media Player, or perhaps Winamp. It’s up to you!
Now that we know what file extensions and associates are, let me tell you why this is important to have file extensions showing. Commonly when people produce viruses, they hide them with known file types such as .MP3, however the file is really an executable like .exe or a .bat file.
