VideoCacheView utility can help you to extract the video file from the cache and save it on your local disk for watching it in the future. VideoCacheView doesn't require any installation process or additional DLL files. It automatically scans the entire cache of Internet Explorer and Mozilla-based Web browsers (Including Firefox) and finds all video files that are currently stored in it. It allows you to easily copy the cached video files into another folder for playing/watching them in the future. If you have a movie player that is configured to play FLV files, and it also allows you to play the video directly from your browser's cache.
What's new in this version:
Version 2.80 now automatically detects and loads the cache of Opera 15 or later (Stored under C:\Users\[User Profile]\AppData\Local\Opera Software\Opera Stable\Cache). Be aware that Opera is now based on Chrome Web browser, and thus VideoCacheView detects the cache files of Opera as Chrome.
