Still the best for finding stuff on disk archives. Been using it for ages. Since the days of the micro-floppy. [yeah, I'm that old].
Please ignore the screenshot. I think it's from the OS 7 days. Maybe a SnowLeopard shot would be a good idea? It works fine on Snow Leopard on Intel Macs and still works fine on old G3 and G4 Macs running Tiger, as well. The competition cannot make that claim.
If you have a lot of archived DVD's, CD's, DVD Ram, MO's, Hard Disks, and, yes, Floppies, then you need this app.
Tried all the others, DiskCatalogMaker, CDFinder, etc.. But they all try to add too many features that slow the app down. If you need to catalog your media [image,video,graphics, etc] then use a dedicated media cataloger.
I use Toast for it's Disk Spanning feature, making archive disks and sets that are individually Finder-Readable. I use DiskTracker to catalog all my disks and can quickly find any file going back to the early '90's.
DiskTracker is dedicated to finding files in Finder-Like fashion, on all your off-line disks. It has the most powerful search engine of the bunch and that is by far the most important feature. Without a good find function, what's the point?
