I have forgotten the name of the software although I remember that I bought it to use to catalog all of my CDs, floppies, Jazz drives, etc. -- and I can't find the package where I stored my old Inside Mac Games CDs (and my old Mac running OS 9 stopped working

This was a long time ago (I think before Mac OS X) when Inside Mac Games would send out a CD with Mac game demos, freeware, updates, and stuff to people who subscribed to these CDs.
Also, does anyone use something similar that works on a Mac (just in case that company no longer updates/makes the app .
Thanks for any info.
