  • ChromeCacheView - Cache Viewer For Chrome Web browser

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, aslong 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 fileswon't work in the new versions of Opera.I hope that this problem will be fixed in future version.
