Haxial DiskCatalog is a utility for cataloging CDs, hard disks, folders, and any other type of disk. It allows you to browse the contents of disks without having to find them and insert them into your computer. More importantly, you can search all of your disks at once, and it will display a list of all the files found, and their location. When you're looking for a file and you don't know where it is, this is much easier than manually searching all your disks. It is designed to be very fast -- search results usually appear instantly. It can also export catalogs to tabbed text files for importing into a spreadsheet, database, etc.
