Being a HUGE downloader of softwares, music and movies; my hard disk is always near to full. I’ve to burn all of that on DVDs to keep some space available. After burning that all on DVDs, if I ever want to re-use any of that, it becomes really hard for me to search that in different DVDs. Cathy is an extremely small (44 KB), useful & free application that comes really handy in such situations. Cathy can be used to index and catalog CDs, DVDs and even hard disks. You can then easily search Cathy for anything that you ever stored on any of the storage devices and Cathy will tell you the location and name of the storage device. So if you burn lots of DVDs and CDs, this is a must-use tool for you guys.
