New file in sims 4 folder

My hubby was looking at my computer (game rig has gotten incredibly slow and wouldn't allow me access to certain programs) so he went through my Sims 4 Folder. "What's this, he asks?" Leave it alone it's part of my game., I say. Turns out the picture, which took forever to coalesce was from the Origin page for EL. I was worried should he start deleting things like a maniac. You know these Engineers, how they love to change things! LOL Turns out, my rig must go see a computer doctor. Appears to be slightly ill. This after my security program removed certain malware just the day before. I also need an OS upgrade. Luckily, I've got this relatively new laptop to come here with and to also play my game. :)
