Strange cookies?

Until recently, if I wanted to just check on what cookies were on my machine, I would go to

 

C:/Users/Me//AppData/Roaming/Microsoft/Windows/Cookies/Low

 

there I would see the cookies listed in this way

 

"myname" @symantec.com

 

or

 

"myname" @yahoo.com

 

 

But today when I take that same path, I see this instead

 

just a random group of numbers and letters 8 long, eample

 

NT34K3TH

 

they are shown to be text documents like cookies are and when I open them up (the text documents) they do show what the website is and all are legit

 

Any thoughts as to why they don't show like they always have?  I use Vista Home Premium 32 bit with Vista SP2
