How to "open" backup files without original job

Hi,

I've just installed Backup & Recovery 16 Free and cannot see how to do something incredibly basic.

I want to know how to open and extract files from a backup set. The user manual tells me I have to open the backup job and then use that to restore from the backup data set. Suppose I am not in possession of the original backup job ? This would surely be a very common situation where I have the backup data set but not the job. There seems to be no way to point the application to a set of backup files and then tell it to restore from it.

Am I missing something really obvious ?

Any help gratefully received !

Thanks
