Cache View - description from Softdepia.com:
Cache View is a viewer for the Netscape Navigator (and Mozilla!) and Internet Explorer caches. You can open the cached files for viewing, and copy or move them out of the cache. It will even reconstruct the names and directory paths of the files for you. It makes emptying your file caches easier than ever. The intuitive Windows 95 interface makes Cache View easy to learn and even easier to use. Support for Internet Explorer, and Netscape V2 through to V6.
Cache View is a "Free to try" program. You can download and try it for an evaluation period.
