Notice: This tool only works on old versions of Opera (Below version 15). Today Opera is based on the code of Chrome Web browser, so you should use
ChromeCacheView instead of this tool.
Description
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.
System Requirements
This utility works on any version of Windows, From Windows 98 to Windows 7.
However, for Windows 98/ME, you have to download the non-Unicode version.
You can use this utility even if Opera Web browser is not installed on your system, as
long as you have the entire cache folder that you want to inspect.
Know Problem
The new version of Opera now save or compress the files in different format and put them in a subfolder under the main folder.
Currently, OperaCacheView cannot extract the files in the new format, and thus copying the cache files
won't work in the new versions of Opera.
I hope that this problem will be fixed in future version.

Using OperaCacheView
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).
