When you say "recorded" I suppose you mean added to / stored into each
database, right ?
If that's right, then I think you can add as many items as your storage drive can hold....
AFAIK, there's no Album limit although I remember something about a "2 Gb" limit size for Access files, and since CATraxx uses standard Access databases, it could be related...
But I strongly suggest waiting for a Fredrik's feedback to know if that's correct.
You can also work with an unlimited number of databases.
Hope this helps & have a nice weekend.
