This could honestly be open to interpretation. I took it as what he really needed was the last 8 records thats currently in the directory. Anyways, Thanks for pointing that out, I retract any and all suggestions.
Even the OP stated this would work, but he needed it to run every hour, so I modified it somewhat to show him another way. I am only giving suggestions/opinions/options in hopes it will make him think/tinker more and figure it out on his own. I also search for code and modify it as I need
I cant figure it out myself.
