QuickBooks TLG Data Recovery

How to Recover the QuickBooks TLG File

QuickBooks TLG Data Recovery - How It Works?

Has your QuickBooks .QBW file disappeared or become misplaced? Did your QuickBooks data file accidentally end up in the recycle bin? Don't panic if your .TLG file is still intact; by reapplying the .TLG file to a previous backup, you can achieve a full recovery!

To retrieve all the lost data, the QuickBooks TLG Recovery Service replays the information from the Transactional Log File (TLG) into a prior backup (QBB or QBM) or a duplicate (QBW) of the data file.

Are you a QuickBooks user relying on Intuit Data Services to salvage data from damaged or corrupted QuickBooks data files? The recovery process can be time-consuming, leaving you without access to your data for days. However, QuickBooks Auto Data Recovery (ADR) offers a rapid solution for data recovery in cases of loss or corruption. Intuit recommends using the ADR feature only after attempting other appropriate troubleshooting solutions.

QuickBooks Auto Data Recovery (ADR): What Is It and How Does It Work?

QuickBooks Auto Data Recovery (ADR) is an embedded recovery feature within QuickBooks Desktop (QBDT). It facilitates the retrieval and restoration of lost QuickBooks data by executing one of the following actions:

  1. Utilizing the latest Transaction Log (.TLG Log) file and a copy of the Company file (.QBW) to restore recent transactions.
  2. Employing both a copy of the .QBW file and .TLG file to recover all data, excluding transactions performed within the last few hours.

Before we delve into the data recovery solutions offered by ADR, here are some essential points to consider:

  • The ADR feature is accessible in QuickBooks Pro, Premier, and Enterprise Editions for Windows but is unavailable in Accountant Editions.
  • Remember that QuickBooks cannot generate an ADR file exceeding 1.5 Gigabytes. Suppose you must recover data from a corrupted backup file larger than 1.5 GB. In that case, you might consider using a specialized QuickBooks data recovery tool capable of repairing and recovering backup files of any size.
  • Ensure your QuickBooks Desktop is updated with the latest updates installed.

Solutions for Recovering QuickBooks Data Using the Auto Data Recovery Tool

There are two primary solutions for recovering QuickBooks data using the ADR tool:

Solution 1 – Using the.TLG File with the .QBW.adr File to Recover Recent Transactions

Follow these steps:

  • Create a new folder on your Windows desktop (let's call it QBTest).
  • Locate the Folder where your company file is stored. If you need clarification about the file's location, access the 'Product Information' screen and then the 'No Company Open Window' to find it.
  • Within the company file's Folder, search for a .tlg file with the same name as the company file. If you don't find a file with a .tlg extension, follow these steps to display file extensions: Open File Explorer (Windows+E), click Organize and choose Folder and search options. For Windows 10, 8.1 & 8 systems, click View, select File name extension, uncheck "Hide extensions for known file types," click Apply, and then OK.
  • Copy your company's Transaction Log (.TLG) file and paste it into the QBTest folder created earlier.
  • Access the QuickBooksAutoDataRecovery folder in the same directory as your company (QBW) file.
  • Copy and paste the .QBW.adr file into the QBTest folder. 
  • Creating both a .TLG and .QBW.adr file in the QBTest folder.
  • Right-click the newly renamed QBW.adr file in the QBTest folder and choose Rename. Delete ".adr" from the end of the file name.

Solution 2 – Using Copies of Company Files and Transaction Log Files to Recover Transactions

  • Launch QuickBooks and access the company file located in the QBTest folder.
  • Utilize your account register to confirm the presence of all transactions.
  • Proceed to assess the integrity of the recovered data by navigating to File > Utilities > Verify Data.
  • If the duplicate of the company file contains the desired data, relocate the corrupted company file (QBW) to a separate location.
  • Finally, save the QBW file copy from QBTest to its original location.

All transactions except the last 12 hours of transactions can be recovered by using the .QBW.adr and .TLG.adr files. To do this, follow these steps:

  • Create a new folder, such as QBTest, on your desktop.
  • Within the Folder containing the QBW file, search for the QuickBooksAutoDataRecovery folder.
  • In the QuickBooksAutoDataRecovery folder, locate the .TLG.adr and .QBW.adr files bearing the same name as the company file.
  • If you can't identify the .QBW.adr and .TLG.adr files, they might be hidden, necessitating a change to file extensions display settings.
  • Copy and paste the .TLG.adr and .QBW.adr files into the QBTest folder.
  • Remove ".adr" from the end of the Transaction Log and Company file names in the QBTest folder.
  • Open QuickBooks® and access your company file within the QBTest folder. Verify the presence of all transactions through your account register.
  • Use the Verify Data utility (File > Utilities > Verify Data) to check the accuracy of the recovered file's data.

If the copy of the company file in the QBTest folder contains the data you require, move the corrupted QBW file to a different location and save the composition of the QBW file from QBTest to its original location.

Additional Steps for Recovering Lost QuickBooks Data

If QuickBooks Auto Data File Recovery falls short in restoring the lost data, consider using SMB Repair for QuickBooks Software. This tool can repair severely corrupted company files (QBW) and backup files (QBB), quickly recovering all data.

  • The software will preview recoverable Company file data from your QBW file. To preview recoverable data of Customers, Vendors, and Employees, click on the respective tabs.
  • After verifying the recoverable data's integrity in the preview window, click 'Save' to save the recovered file. In the 'Save File' window, click 'Browse' to choose a location for saving the new company file with the recovered data. Alternatively, you can select a QuickBooks backup file (QBB) for improved data recovery. Save the recovered data by clicking the 'Save' button, which will be saved in the selected location.

Frequently Asked Questions

What is the QuickBooks transaction log file, and what purpose does it serve?

The QuickBooks transaction log file (.TLG) is a log of all the changes about to be made to the company file (.qbw) before they are recorded in the company file. It is automatically created by QuickBooks and stored in the same folder as the company file. QuickBooks uses this file to transparently complete the recording of transactions that were not wholly saved in the company file due to a lost connection. Additionally, it can be used to recover from a damaged company file when used in conjunction with a QuickBooks backup file (.qbb).

When is the QuickBooks transaction log file reset, and how can it impact QuickBooks performance?

The QuickBooks transaction log file is reset in two specific situations: when you complete a manual backup in QuickBooks (not a scheduled or online backup) and when you restore a portable company file (.qbm). If the company file doesn't match the transaction log file, it can trigger a reset. Managing the transaction log file is essential since large files can negatively affect QuickBooks' performance. Users can request the removal of .TLG files to maintain optimal performance.

What is QuickBooks Auto Data Recovery (ADR)?

QuickBooks Auto Data Recovery (ADR) is a built-in recovery feature in QuickBooks Desktop (QBDT) that helps retrieve and restore lost QuickBooks data. It uses the latest Transaction Log (.TLG Log) file and a copy of the Company file (.QBW) to restore recent transactions or both .QBW and .TLG files to recover all data, excluding recent transactions.

In which QuickBooks versions are ADR available?

ADR is accessible in QuickBooks Pro, Premier, and Enterprise Editions for Windows but not in Accountant Editions.

Is there a size limit for ADR files and alternative options for larger files?

If you need to recover data from a corrupted backup file larger than 1.5 GB, you might consider using a specialized QuickBooks data recovery tool capable of handling larger file sizes. Additionally, it's essential to ensure your QuickBooks Desktop is updated with the latest updates installed for optimal functionality.

What is a QuickBooks QBW TLG file?

The QBW .TLG file, which stands for Transaction Log, serves as a safeguard to aid in data recovery in the event your primary file becomes corrupted. This file stores copies of all the transactions generated in your company file, effectively acting as a backup. In theory, Intuit Data Services can leverage this information to restore data that has been compromised.

Is it safe to delete the QuickBooks TLG file?

While it's accurate, it's strongly advised not to delete the TLG file. QuickBooks will automatically generate a new TLG file when you access your company file in a different location. Removing the TLG file could also lead to permanent data loss if any of your main files experience corruption.

How do I reduce the size of a TLG file?

Under no circumstances should you delete the TLG file. The simplest way to reduce the size of the TLG file is to create a backup of Quickbooks from within the application. Go to the file menu, choose "create backup," and follow the provided instructions to back up Quickbooks and trim the TLG file.
