How to find B2D files relating to backup set?

Hi,

I added a file server yesterday to my BE 2012 server and created a backup job. There is about 7GB of data in the file share and BE reported a succesful job and stated that it backed up all the data. However, I cannot for the life of me find the file. There is only ONE file in the storage repo that I pointed the job to but it is only 88MB! Where is the REAL B2D file?

When I click on "backup sets" and then double-click the set it created last night there is no where (that I can find) that shows which B2D files are associated with the set. Why?

Thanks!
