Using VideoCacheView
VideoCacheView doesn't require any installation process or additional DLL files. In order to start using it, simply run the executable file (VideoCacheView.exe)

After running VideoCacheView, it scan the cache folders of your Internet Explorer and Mozilla browsers, as well as the temporary folder of Windows. Wait 5 - 30 seconds until the scanning process is finished, and the main window of VideoCacheView should display all the video files that are currently in cache.

After the video list is displayed, you can use one of the following options, assuming that the video files are stored in the cache ('In Cache' = Yes):

Play Selected File: Allows you to play the video file directly from the cache, assuming that you have a video player that is configured to play .flv files.
Copy Selected Files To: Allows to copy the video files from the cache into another folder, so you will be able to play them in the future.

If you have a video file that is not stored in the cache ('In Cache' = No), you can use the 'Open Download URL In Browser' option (F8) in order to download the video file. You can also use the 'Copy Download URLs' option (Ctrl+U) to copy the download URLs to the clipboard, and then use then in your browser or in other download software.
Be aware that some Web sites may not allow you to download a video file in this way.

Flash Video Files In Temporary Folder
Each time that a Web browser plays a Flash video file, the .flv file is saved into the temporary folder of Windows. Normally, you cannot copy this temporary file to another folder, because the flash player locks the file exclusively. Also the file is automatically deleted when you close the Web browser.

VideoCacheView displays the flash files in the temporary folder, and allows you to copy them into another folder. VideoCacheView can handle temporary flash files created by Internet Explorer, Mozilla/Firefox, Opera Web browser. Be aware that you must wait until the browser finish to download them. otherwise, the copied files will be corrupted.

Playing Video Files Directly From The Cache
Most Web sites today use Flash video files (.flv extension) for playing video inside the Web page.
VideoCacheView doesn't provide a build-in video player, but if you already have a video player that is configured to play .flv files, VideoCacheView will be able to use it for playing the video files directly from the Web browser's cache.
