• First, go to the company file location, copy the file path from the address bar, and paste it into Notepad.
• Next, count the characters and the spaces to ensure that it isn’t longer than 210 characters.

Once done, try to restore the company file backup again. If you are still unable to restore the backup copy, you can use the ADR tool to recover the data using the next solution.

Solution 6 – Recover Lost and Damaged Data with the ADR Tool

If your company file is damaged and you aren’t able to restore its backup copy, the next solution is to use the ADR tool. This tool allows you to recover all or mostly all of the lost or corrupted data. QuickBooks Auto Data Recovery feature can help you recover the lost file by –

Points to Consider:

• The ADR feature is available to be used in QuickBooks Pro, Premier, and Enterprise Solutions for Windows; however, it is unavailable in Accountant Editions.
• This tool has file size restrictions, and QuickBooks will only generate an ADR file if the backup does not exceed 1.5 GB in size.

Use the Original .TLG File & the ADR Version of the Company File to Recover Recent Transactions

You can utilize the original Transaction Log file and the ADR version of the company file to recover all recent transactions by implementing the steps given below –

• Open the Company File Folder and locate the file with the .TLG extension that has the same name as your company file. If you cannot locate the .TLG file, perform these steps to enable file extensions on your Windows –
  • Press the Windows + E keys, open Windows File Explorer, and select Organize.
  • Select Folder and search options, click Hide extensions for known file types, then hit Apply and OK to save the changes.
• Copy the corresponding .TLG file of your company file, paste it to the QBTest folder, then access the QuickBooksAutoDataRecovery folder from the company file location.
• Now, copy the .QBW.adr file, paste it into the QBTest folder, and you should now see a .QBW.adr and .TLG file in this folder.

• Ensure that all transactions are present, then go to the QB File menu and select Utilities.
• Now, select the Verify Data option to check the data integrity of the recovered file.
• If this company file copy confirms data integrity, move the damaged company file to another location and transfer the copy from the QBTest folder to the original location.

Once the process is complete, you will have successfully recovered all the recent transactions. However, if you wish to recover all except the last 12 hours of transactions, perform the steps given in the next section.

Utilize the .TLG.adr and .QBW.adr Files to Recover All Except the Last 12 Hours of Transactions

You can use the ADR version of both the .QBW and .TLG files to recover all but the last 12 hours of transactions in the following manner –

• Create a new folder named QBTest on your desktop, then open the company file folder and find the QuickBooksAutoDataRecovery folder. If you can’t locate the company file folder, check the file location from the Product Information screen (press F2 or Ctrl+1) or from the No Company Open Window.
• Next, look for the .TLG.adr and .QBW.adr files with the same name as your company file.
• If you can’t locate the .TLG.adr and .QBW.adr files, you need to enable the file extensions. For this, follow step 3 of solution 1 – “rename the QuickBooks network data and transaction log files” of this section.
• Now, copy the .TLG.adr and .QBW.adr files and paste them into the QBTest folder created above, then right-click the .QBW.adr file.
• Choose Rename and remove the .adr from the end of both these file names, which should give you .QBW and .TLG files.
• Further, open QuickBooks and access the company file saved in the QBTest folder, then use the account register and review the transactions.
• Verify that all transactions are present, then go to the File menu, select Utilities, and click Verify Data.

• Run the Verify Data tool, check the data integrity of the recovered file, and ensure that the file is free of issues.
• If this copy of the company file confirms data integrity, move the damaged company file to another location and transfer the copy from the QBTest folder to the original location.

• Enter the port number in the port exceptions list, then select Next, hit Allow the Connection, and click Next again.
• Make sure all profiles are checkmarked (if required), then select Next and create a new rule named “QBPorts(year).”
• Once done, click Finish, and your port exception rule will be created.

Once the exception rules for QB are successfully added, access the app in multi-user mode or over the network from the host computer. Access the company file and review the status of the error. If you still experience the error code, create firewall exceptions for QuickBooks executable (.exe) files in the next section.

Add Firewall Exceptions for QB Executable Files
