Well, I bought the SafariCacheExplorer application which was advertised to separate all the individual parts and files of Web pages and to download them to your computer, especially if you want to retrieve images, videos, etc. embedded in Web pages and don't want to search through the HTML code, which is what I do.
I bought this application since Web(cache)Browser stopped working with Mountain Lion and Safari 6.0.x, but I didn't fully read the Web page for SafariCacheExplorer as it doesn't say it's compatible with Mountain Lion and especially Safari 6.0.x.
Update II.--The company sent me an e-mail confirming it is Mountain Lion and Safari 6.0.x compatible which I've proven to myself is and works. They need to update their Web page about this application, if they haven't already.
