I don't know when it happened, but when I tried to find a pile in my AppData\Local in File Explorer, I discovered that AppData wasn't there. When I searched for AppData, File Explorer gave a long list of files, but clicking on one of them. When I searched for AppData\local I found a few files, but not the one I was looking for. When I looked for the files in Command Prompt, they were all there.
Is this a problem with my file explorer? I do have the view hidden files enabled.
