If you don't like drilling down into the usage report, here is a SQL query that you can run to find usage data either for all files that have been metered or for a specifc file:
SELECT rf.Name AS [File],c.Name AS Computer,wu.UserId, ms.[Month Year],ms.[Run Count],ms.[Last Start] FROM vAMMonthlySummary ms JOIN vComputer c ON ms._ResourceGuid = c.[Guid] JOIN Inv_Global_Windows_Users wu ON ms.UserGuid = wu._ResourceGuid JOIN RM_ResourceFile rf ON ms.FileResourceGuid = rf.[Guid] --WHERE rf.Name LIKE '%part of filename%' --provides data for specific file ORDER BY c.Name,wu.UserId ASC
