Deleting Write Protected files?

Strange thing happened today. A music file which I've had for almost a year stopped working and became "Write-Protected" So I couldn't move it.

How do you delete corrupt files that are Write Protected?

Try that. Install then when install right click-> Unlocker-> Unlock I think.

if not burn to a cd and the protection should come off
