Thank you @Harwinder-singh, The list I have is just file names and it is in quantity of 45,000 names.  I am new to AEM and feel your second option is what I'll need to do.  Where do I go to learn how to do the Groovy scripting? 

I have a list of file names in Excel and would like to link to the SQL back end to verify each of those file names exists in AEM.  How can I accomplish this?
