Best way to access AppData is via Explorer.exe's left-sde tree-climber. I believe you have already done Tools...down to Navigation Panel, and checked the two choices in there. Also, make sure to checkmark show all hidden files and their extensions, show all folders and their paths, etc. in the other section. And, Got Milk? -- I mean -- Got Backups?
well-balanced, well-configured mult-layered defense is best
