Hello Abdou, and welcome to Seven Forums. C:\Users\ras\Cookies
is a junction point for backwards compatibility, and not a actual folder or shortcut. You will not be able to open this location no matter what method you try.
The location for your cookies is actually at the two hidden
protected operating system folder locations below. You could also type shell:cookies
in the Run command dialog instead of the full paths below though. Cookies - Delete
Hope this helps,
