What Causes QuickBooks Error Code 80070057?

Opening the file directly (e.g., from File Explorer) rather than through QuickBooks can cause this error.

3. Network or Server Configuration Issues

Workstations may not be properly connected to the server where the file is hosted.

4. Damaged File Extensions

The company file’s extension may have been altered or corrupted.

5. Outdated QuickBooks Version

How to Fix QuickBooks Error Code 80070057

Below are proven methods for fixing this error based on the underlying cause. Start from the top and work your way down.

Fix 1: Always Open Company File From Inside QuickBooks

This is a simple but often overlooked solution:

  1. Open QuickBooks Desktop.

  2. Click File > Open or Restore Company.

  3. Choose the company file from the proper location.

  4. Avoid double-clicking the file in File Explorer.

Fix 2: Rename the .ND and .TLG Files

QuickBooks uses these files to access your company file in network mode. If they are corrupted, the error may pop up.

  1. Navigate to your company file folder.

  2. Find the files ending with .ND and .TLG (e.g., companyfile.qbw.nd).

  3. Rename them to:
    companyfile.qbw.nd.old
    companyfile.qbw.tlg.old

  4. Restart QuickBooks and try opening the file again.

Fix 3: Run QuickBooks Database Server Manager

If you're working in a multi-user setup:

  1. Open the QuickBooks Tool Hub.

  2. Click Network Issues and open the Database Server Manager.

  3. Browse to the folder containing your company file.

  4. Click Start Scan.

  5. Once done, try reopening the file.

Fix 4: Check and Correct File Extension

QuickBooks company files should have a .QBW extension.

  1. Right-click the company file and select Properties.

  2. Under the General tab, check the Type of file.

  3. If incorrect, rename it with the .QBW extension.

  4. Click Apply > OK.

Fix 5: Turn Off Read-Only Mode

If your file is in read-only mode, QuickBooks might throw this error.

  1. Right-click your company file and select Properties.

  2. Uncheck the Read-only box if it’s selected.

  3. Click Apply, then OK.

Fix 6: Temporarily Disable Antivirus and Firewall

Your security software may be interfering with QuickBooks:

  1. Temporarily disable your antivirus or firewall.

  2. Try opening the file again.

  3. If successful, add QuickBooks as an exception in your antivirus settings.

Fix 7: Update QuickBooks

Using an outdated version? That could be the root cause.

  1. Open QuickBooks.

  2. Go to Help > Update QuickBooks Desktop.

  3. Click Update Now, then Get Updates.

  4. Restart QuickBooks and try accessing the file.

Fix 8: Move the File to a New Location

There might be permission issues with the original location.

  1. Copy the company file to a different folder (e.g., Desktop).

  2. Try opening it from the new location.

  3. If it opens, the original folder had permission issues.
