If those are Lacerte files, and I doubt they are, they are Benefit(Form 5500) client files for the years 2002 or 2012. It would be unlikely you would be able to gain access to this data unless you know a CPA that has the correct/licensed version of Lacerte. The Lacerte BDX files are also very small. The largest is 4 KB while most are only 1 KB.
