i am currently working with MP4 files in combination with my SONY PSP. normally i have no MP4 viewer on my PC so any file logos have the "windows cannot open this folder" logo . but i tried to look at a file using wordpad, and now all the MP4 files have been given the WORDPAD logo. can i change a settingi so any MP4 file displays the "windows cannot open....." logo again

Open up My Computer, click on the C drive. Then up at the top line under tools select Folder Options. Click on File Types and scroll down to the MP4 item and select change.

Another alternative, you could download Quicktime, and that also would change the icon and allow you to view them.
