A free program for analyzing selected files by Patrick M. Koll, creator of the popular SpyBot Search & Destroy.

FileAlyzer allows you to analyze a selected file and access a lot of detailed information about it. Among them you will find everything that is normally available via Windows Explorer's context menu (e.g. creation date, size, version, attributes, etc.), as well as the checksums of CRC-32 and MD5 files, hexadecymal preview of files, ID3 tags for mp3 files and many others.

The author recommends it for more advanced users as a good addition to SpyBot in advanced mode (it can be used as a standard file browser).
