  • Open the company file, go to File, and then select Utilities.
  • Select the option ‘Stop Hosting Multi-User Access.’

  • Next, navigate to the location of your .QBW file, and copy the file’s path from the address bar.
  • Save the location path of the company file on a notepad, count the characters and the spaces in it. For example: C:Documents and SettingsAll UsersDocumentsIntuitQuickBooksBackup Company FilesQuickBooks 2021Backup_company_file.qbw is 125 characters.
  • Again try restoring the company file from backup.
