Error: "The file cannot be accessed by the system"
The error message "The file cannot be accessed by the system" during backup of the user profile folder.
The cause is the WindowsApps folder. This folder is a location for installed Windows desktop applications. It was introduced with Windows 8 and is used as a location for installed Windows Store apps. Read/Write permissions are limited by operation system.
