I changed it today thinking that the new SSD has more space than my c drive which is also an SSD. Deleting the preferences didn't alter the Conformed Media Cache as set by me today. I tried to put the second option back, but when I browse for the folder within the preferences framework I cannot see it. I changed the 'Disk Cache' to the new SSD and then also changed the second option 'Conformed Media Cache' to the new SSD - then watching some videos I noticed others have only changed the 'Disk Cache' and left the second option as c:users ameAppDataLocalTemp.
