You have to associate where the data was placed, literally as tapes are finite in size and files shouldn't be infinite. It's a way to manage the correlation. Don't think that files are any different than tapes, they have much the same limitations except for the obvious like wear. >Why doesn't a Device (in my labs, I'm only using the File media type) >have properties to define how large it is, rather, it's parent Volume >specifies that?

The device doesn't have a size because that's limited by the volumes:) What happens when you add more tapes/files and/or get bigger ones? Device is just that, a device to write with. >How often can I expect to use the same Fileset or Schedule for similar >machines?

Not off topic, one has to learn at some point.
