TLG file is important in QuickBooks in QuickBooks Desktop. It is used in Auto Data Recovery, a process that uses the.ADR file type to recover data from your QuickBooks company file. It is utilized in the same folder next to the.TLG file. This process is frequently used to recover any impacted transactions from your data file when QuickBooks data corruption appears to be irreversible in your organization file. This is a complex process that requires attention to detail and exact steps to follow.
As you continue to use your QuickBooks company file, you should be aware of the implications around the Transaction Log, or TLG file, and its growth. It will have an impact on how well it works for you and your business if your TLG file ends up larger than your corporate file, particularly when it is being utilized over a network. Additionally, because it comes included with it, it will have an impact on the size of your backup files. It is not possible to resize this using a scheduled backup; instead, the simplest solution is to manually create a local backup with full verification enabled.
You will receive a fresh or reset TLG file if the backup is successful. The same issue occurs if you relocate your company’s main file (.QBW) to a different folder. You can encounter a problem if your company file is so damaged that you have no choice but to employ QuickBooks Data Recovery. You might want to hold onto the current TLG file until the issue is fixed or an agreed backup file is restored if data integrity needs to be addressed.
Do you want to know how the TLG file gets affected by the QuickBooks portable file process? You cannot use an older or non-reset TLG file once you have chosen to restore a portable file. However, the file’s use is limited due to Data Integrity concerns, necessitating its recovery via the Auto Data Recovery procedure. Also, by re-indexing company file data in QuickBooks Desktop, portable file generation and restoration using it is a way to troubleshoot data integrity. After implementing this process, if certain data integrity problems persist, you will need to either manually correct the data errors that were discovered in your verification or rebuild findings, or you will need to send the file to a data recovery team.
Your QuickBooks company file is updated as you work with it with the transactions you enter. QuickBooks will save transactional data in the Transaction Log (TLG) file in addition to updating the company file. All of the changes that you make to your company file are being tracked by QuickBooks. It is not unusual for the TLG file to see the QBW file in size as it keeps growing.
Some users have informed me that, at least when the file is quite large, you may notice a drop in system performance as the TLG file grows. Not able to independently verify that myself. The performance and cost of backup tools and processes may be affected by the larger file size.
Interestingly, you could also notice a file with the file type ND. This is the NetConnect file, and it contains data about several users’ access to your company file. You should not remove it.
In your regular QuickBooks operations, the TLG file serves no purpose. It is not visible to you, and its existence has no bearing on how you use QuickBooks.
The TLG file is useful for restoring data. The TLG file can be used with your latest backup to restore transactions that have been entered since that backup if your company file is lost, destroyed, or otherwise compromised. Here are a few simplified examples.
It is not possible to take a backup file and update it with the transaction log using a user-accessible utility tool. A few options available to you are:
Each of these services has a price that you must pay in addition to a turnaround time that prevents you from adding or changing any information in your QuickBooks repair company file.
Okay, so now that we have established that the file becomes huge and takes space (especially if you are copying backups and this file to a CD or other media), that it may slow down performance as it grows larger, and that you must pay money to use it to recover data, we can go on.
On the one hand, if you have a solid backup plan (see, for example, Backing Up QuickBooks Data), you can easily restore your backups in the event of a disaster because you will be backing up frequently and in multiple locations.
Is the TLG file not required? To be honest, I disagree with that. In my opinion, you should seize every chance for data security that comes your way. This means that you have to make use of QuickBooks’ backup feature and add the TLG file to the list of files that are regularly (or frequently) backed up. It gives your backup plan an additional layer of security in case something strange happens to you. For example, occasionally your QBW file may include corrupted data that is irreparable. You may not notice the damage right away, which means that your daily backups may potentially be compromised. To restore yourself to the state you were in before the damage, you might require a good QBB backup and a matching TLG file.
Keep in mind that QuickBooks will create a new TLG file if you remove the old one, but its usefulness will be restricted due to its incompleteness.
The general idea behind handling backups with TLG files is that QuickBooks will create a file with the QBB file type and remove the TLG file when you create a backup using the backup tool (from the File menu). You don’t need that transaction log because all of the transactions are kept in the backup. The TLG file will then begin to grow once more, containing all of the transactions since the backup.
But not every backup file is created equal. The TLG file will only be deleted by QuickBooks if you manually backup your data and enable verification.

The TLG file is not cleaned and your QBB file cannot be used with that TLG file if you do not choose the full verification. Furthermore, backup must be done manually by choosing backup from the File menu. This will not be done by a scheduled backup, even if full verification is chosen. Backups created using your backup software or using QuickBooks Online won’t work either.
Your company file and the TLG file need to match. For example, you cannot use it to “merge” transactions from a different computer (such as your home laptop) to your business desktop. QuickBooks will detect a difference between the two TLG files and “reset” the TLG file, deleting all of the transactions that were previously entered in the log, if you copy a TLG from your laptop to your office computer.
It’s important to note that creating a portable company file has no bearing on your TLG file; however, if you later RESTORE a portable business file, the TLG file will be reset because the portable company file won’t match the TLG file.
Before creating the backup, here are the company file (very small) and the TLG file:

Following a manual backup with the verify option enabled, here are the files.

Thus, below are a few recommendations:
Depending on the size of your current TLG file, QuickBooks may not be able to run a backup with full validation due to the current TLG file size. If this is the case, we always suggest you contact your local ProAdvisor or QuickBooks specialist before taking issues into your own hands.
Most probably, if your TLG file size has increased exceptionally large, the experts will move or rename the current TLG file before running the backup routine with full verification. Many experts will change your TLG file name to “filename.TLG.DATED” and this will allow you to run the backup with full verification. Later, you can remove or delete the TLG file that you renamed.
Even if there is no daily interaction with the TLG file, you should be conscious of its importance in your QuickBooks company file. In short, always remember:
When performing routine day-to-day chores in QuickBooks, a TLG file is useless. It has no impact on any other work. Data restoration and data recovery from a destroyed company file are the primary uses for the TLG files.
The following factors can result in a TLG file error:
Frequently, when you open your specific QuickBooks software and select the file you want to work on, an error code prevents the file from opening. These QuickBooks error codes look like this:
Often, the only thing to do in cases like this is to remove the TLG file. You won’t lose all of the data in the file if you do this, but you might lose some of the data needed to fully restore the previous backup file. In this case, you should delete the important parts of the file when there is no other choice.
The TLG file can be deleted in the following ways to resolve the error:
Note: This file will open without it and has no errors.
The following must be confirmed before you start the troubleshooting process:
It is expected that by following the above instructions, users will be able to quickly resolve the issue and carry on with their business transactions.
Since deleting your QuickBooks TLG file is far from an ideal solution, there is still a simple way to reduce the size and memory demand of your QuickBooks TLG file.
The simplest way to effectively manage your QuickBooks TLG file involves setting up a routine to create a local backup with full validation directly within QuickBooks. By generating a local backup with full validation, QuickBooks TLG recognizes file redundancy, as any potentially corrupted file can be restored from a recently created backup. This procedure is designed to reduce the size of your current TLG file. To confirm that the TLG file remains manageable, follow a regular schedule of performing backups with full verification.
