It amusing to see the Arizona idiots do not understand how .ldf (SQ logging) and .mdf SQL files work -- when you perform an automated SQL database backup as a restore point -- which is stored off the system via a backup tool and previous versions of the files left on the system are eventually manually deleted to preserve disk space in order to preserve performance.
All of the other claims from these "Arizona Audit" idiots have been found to be full of shiat and roundly laughed at. This one is no different. It's hard to believe the "Cyber Ninja" technical "experts" are so clueless - but they are. Anyone with the slightest amount of IT knowledge is mocking these idiots.
So let me ask what do 2018 and 2019 files have to do with the 2020 election?
