Browser cache locating utility VideoCacheView searches through your browser cache for already-watched videos—so you can copy them to your videos folder. Using the utility is simple—just launch the application and wait while it searches through the cache for each of your browsers (even Chrome!), and then either play the file or save it for later. Using the play function requires a media player that can play Flash files, or you can convert the file to a more compatible format using any number of tools. VideoCacheView is a free download from NirSoft, works on Windows only. While there are any number of ways to download a YouTube video (like Lifehacker's own Better YouTube extension), this utility could come in handy for saving videos from other sites.
