OperaCacheView is a small utility that reads the cache folder of Opera Web browser, and displays the list of all files currently stored in the cache. For each cache file, the following information is displayed: URL, Content type, File size, Last accessed time, and last modified time in the server.
You can easily select one or more items from the cache list, and then extract the files to another folder, or copy the URLs list to the clipboard.

OperaCacheView doesn't require any installation process or additional DLL files. Just copy the executable file (OperaCacheView.exe) to any folder you like, and run it.
After you run it, the main window displays the list of files currently stored in the cache of Opera. If you want to view the cache folder from another location, simply use the 'Select Cache Folder' option (F9), and choose the desired cache folder.
You can select one or more cache files from the list, and than export the list into text/html/xml file ('Save Selected Items' option), copy the URL list to the clipboard (Ctrl+U), copy the entire table of cache files (Ctrl+C), and then paste it to Excel or to OpenOffice spreadsheet. You can also extract the actual files from the cache, and save them into another folder, You can do that by using the 'Copy Selected Cache Files To' option (F4).
Notice: The cache items are added to the cache index file only after you close the relevant window or tab. This means that in order to get the cache items of a page that is currently opened, you must close it, and then refresh the list in OperaCacheView (F5).
