I'd like to delete them.
Do I run any risks by deleting everything in that folder, WHEREVER it may be, now?
PP will rebuild any files it needs when it needs them.
When I go there and try to empty the cache, the application freezes.
So I wanted to delete them manually, by hand, but cannot readily find them anywhere on my computer.
Hence the question?
That screen will tell you where they are. (And allow you to change the location as well.)
