QuickBooks Error 80070057 typically occurs when a user tries to open a company file directly by double-clicking it instead of opening it from inside QuickBooks. This error indicates that the user does not have sufficient permissions to delete files from the particular folder path. To resolve this, users can ensure QuickBooks is set to run as administrator, verify their file permissions, and use the correct way of opening files through the QuickBooks interface, ensuring smoother operation and access.
