Warning: QuickBooks cannot open this file because it exists as a Read-Only file

When trying to open a company file, the following message appears:

Warning: QuickBooks cannot open this file because it exists as a Read-Only file. Please make the file Read-Writable and then try opening it again
Why this is happening

This error can occur when:

  • Opening a company file created in QuickBooks 2006 or later, but using QuickBooks 2005 or earlier to load the data
  • Opening a company file located on read-only media (such as a CD-ROM)
How to fix it

Intuit recommends 3 solutions for this problem. The first solution may solve your problem, or you may need to try all to resolve the issue. For best results, perform the solutions in the order shown.

Solution 1: Rename the .nd file and .tlg file associated with the company data file:

  1. Search the computer for files with extension .nd (Example: *.nd).
  2. Locate the .nd files with the name of the company having trouble opening.
  3. Right-click the .nd file, click rename and type old at the end ( for example, company.nd would become company .nd.old).
  4. Open QuickBooks. 

Solution 2: Verify QuickBooks version last used.

If the company file is not on a CD-ROM and the warning appears, restart the computer and try opening the company again. If that does not resolve the issue, use the following steps to determine the version of QuickBooks that was used to create the file.


  1. Search for the file:
    • Windows 8:
      1. On your keyboard, press Windows and type *.qbw.
      2. Click Files.
    • Windows 7 or Vista (Standard View):
      1. Click the Windows Start button.
      2. In the Search field enter *.qbw.
  2. In the Search Results window, right-click the company file and select Properties. The version of QuickBooks used to create the file appears on the QuickBooks tab, in the Last opened with field.
  3. Open the company file in the same version of QuickBooks that the file was created in.

Solution 3: Move the company file from the read-only media to the local computer.

  1. On your keyboard, press Windows + E to open the Computer window.
  2. Browse to where the file is located using the folder list on the left.
  3. Right click the company file and choose Copy.
  4. Browse to a folder on the local hard drive.
  5. Right click and choose Paste.
  6. Try opening the file in the new location.
