EZ Cat (http://www.loggytronic.com
If you want a solid, few frills file & folder disk catalogue program that is really straightforward to use, try this.
"EZ Cat was originally commercial and after a good few years of success it is now freeware."
No mp3 tags, doesn't look inside mp3's.
But no really awkward interface bugs either- straightforward old explorer style.
By comparison, I found some views in CDVISTA non-intuitive and I was scrambling around to find the parent folder of what I'd found at first.
After trying about 6 freeware programs, I'm surprised I've not found a neater looking program that meets my basic needs.
