The GNOME Disk Catalog

GTKtalog is a disk catalog, meaning you can use it to create a really
small database with images of files and folders of your CD-ROM. So you
can browse all your CDs very quickly and see contents of certain files
(such as tar.gz and rpm files). You can assign each folder and file a
category and a description. You can search for files in your database
with filename, category, description, or file information parameter and
find on which CD the file you are looking for is.
