Hello
To open a file from a backed-up QBD file, you can follow these steps:
Move the Backup File: If your backup company file is on an external device like a USB or a hosting service, move it to your local hard drive first.
Open QuickBooks Desktop: Launch QuickBooks Desktop on your computer.
Restore the Backup:
Go to the File menu and select Open or Restore Company.
Choose Restore a backup copy and then click Next.
Select Local Backup and then click Next.
Browse your computer for your backup company file. It should look like this: [Your company name].qbb.
Select a folder to decide where to save your restored company file. Then click Open.
Note: If you open the backup in the same folder as your existing company file, you may overwrite your data. To avoid this, you can rename your existing company file or the backup so the names are unique, or save the backup in a completely separate folder.
Save the Restored File: When you're ready, click Save. If you see any messages about possibly overwriting your data, select the option that best fits your needs. Don't overwrite anything unless you know you want to.
