Which folder can I find cache files for Safari? Not the cache in ~/library/caches/. I have found it before, with names similar to "FFYWRMQ7RK4CBV2GWNXVTF7IS9DZ9STNWKZHMPPWRI". The folder does not only include images, but also html code. There are no extensions to the files and Finder treats them as "Documents".
Safari stores caches in a variety of locations.
