I had not seen your last post [starting
I need to take a step back here I have trying to do too many things,issues
...]. I was writing my post at the time.
There is a folder C:\Users*YourUserName*\AppData and it does have the subfolders you mention [Local, LocalLow, Roaming]. That is the correct place for it. It was never at C:\AppData or anywhere else. AppData is a hidden folder so you may not always
see it [you can set File explorer to show hidden folders & files].
SFC will not address this issue. It only checks the integrity of a set of Windows system files. No more than that.
What do you mean, "The file structure and layout had been wrong for awhile"?
The only way to restore file structures to what they ought to be is to run a "Repair install" procedure or to do a clean [complete] reinstallation of Windows & all your applications. A Repair install is when you run the installation USB/DVD within Windows
[instead of by booting from it, which would reinstall Windows instead]. A reinstallation would require you to back up all your own files first as everything on the disk would get overwritten.
What was the issue that made you "restore"? And what exactly do you mean by "restore" as there are several things that might be called that. Do you mean you ran a "System restore" at System, System protection, System restore? If so, that is also a very
limited measure and it will have no effect on folder structures.
If you have managed to move folders then Windows cannot think they were critical ones or it would not have allowed you to do it.
Defrag does not restructure any folders either. It does not help with such a problem.
Perhaps a complete reinstallation is the best way forward.
