There are several possible causes for this error:

• The file update process may be faster than the file copy process.
• Your antivirus or security software (such as WebRoot, or McAfee) is conflicting with or blocking QuickBooks.
• The Windows permissions for the folder containing the file are set to restrict access.
• The file referenced in the error is in use or damaged.n
