The folder is here for me:
C:\Users\Forcen\AppData\Local\Google\Chrome\User Data\Default\Media Cache
My chrome exe is located here:
C:\Users\Forcen\AppData\Local\Google\Chrome\Application\chrome.exe
Im using Win7
So Ccleaner is supposed to clean this media cache folder?
EDIT: My mediacache folder is pretty empty now, maybe it was ccleaner, not sure.
