ultra catalog is a cd/dvd collection organizer program. it may be used as a catalogue of cd/dvds. after creating the volume, ultra catalog stores file and folder names in tree, and allows searching all the files from the collection cd/dvds without need to place them in cd/dvd reader. ultra catalog may place in the volume any windows folder not only folders on cd/dvds. this program is created to prevent that and to reduce the time you need to a minimum. it may be used in another way if you want of course. what we recommend you is to write with permanent marker on the cd/dvd the numbers you create in volumes part in the ultra catalog and place them row or column or in holder of some kind. each cd/dvd you take out should be later placed on it's place back, to prevent further time consuming procedures.the ability to add files and folder tree's from unspecified places make it useful whatever your media is, until it supports the windows file system.
