About Decache
Decache is a Windows tool that scans web cache folders for video files and compares them with metadata for lost media, with a focus on deleted YouTube videos. The project's homepage states that found videos are compared against metadata for more than 100 lost YouTube videos.
It can be started from a file explorer window or from the command line by supplying a folder path. Command-line switches control whether unindexed videos are kept and how errors are handled. The project states that it runs on Windows XP and later.
