Just plugged an external hard drive into my computer (as I have for years with any computer I've owned) and clicked on a folder to search for a file, and up popped the message:
"This file does not have a program associated with it for performing this action. Please install a program, or if one is already installed, create an association in the Default Programs control panel."
I can't open the folder??!!!
Running windows 7 on an HP desktop computer less than 2 years old that seems to otherwise be working just fine.
