    How to Fix Corruption in QuickBooks Company File?

    A corrupt QBW file can be repaired manually, by using free tools or with the help of a professional QuickBooks Company File Repair software.

    Method 1 – Manual Method to Repair QuickBooks Company File

    You can try to manually repair the QBW file by using Verify & Rebuild Data utility using the following steps:

    1. Open the data file and log-in as administrator.
    2. Select the Single User Mode and then initiate data verification by clicking on File > Utilities > Verify Data.
    Instructions for opening the data file, logging in as administrator, selecting Single User Mode, and initiating data verification through the File > Utilities > Verify Data option.

    The ‘Verify’ process could take some time depending on the size of the file. If this process takes too long or does not complete, you should do a complete rebuild as follows:

    1. Make a local copy of the data file from the server.
    2. Enable temporary hosting on the machine where it is copied (if required) and open the file and log-in as administrator.
    3. Click on File > Utilities > Rebuild Data.
    Perform data file copying, enable temporary hosting if necessary, log in as administrator, and initiate a data rebuild process by clicking File > Utilities > Rebuild Data.

    Once the rebuild is complete, save a copy of the repaired QBW file on the local machine as well as on the server. Refrain from hosting the file on the local machine and give the new file a different name than the original file.

    Note: Complete rebuild takes even more time than the ‘Verify’ process. Until the process finishes, take care not to interrupt this process at any cost. If possible, do not use using the machine while the process is running.

    Method 2 – Free Tools

    Though the manual method is simple to implement, it often takes a lot of time to complete. A better approach could be to use a free QuickBooks Company File Repair tool.

    3. An enlightening blog about QuickBooks. I didn’t try the full version of tool yet. It has a user friendly GUI to understand it’s working.

    4. I like the way you describe about the main reasons of corruption and there solutions. I tried a free tool to repair my corrupt .QBW file but, I think it’s only work for the minor level of corruption. Thanks for sharing this knowledge with readers.

    5. Informative blog about QuickBooks file repair. I am using the USA edition. Yes the file size and chances of corruption are directly proportional to each other. So always maintain the file size.

      1. Hi Liza,

        Just connect the pen drive to your laptop/desktop and copy the file on the desktop. Now start the tool and select the corrupt file to repair it. The tool will show the preview of the corrupt file.

    6. I am using QB2009 and I want to restore a back up copy. The restore option won’t work since I lost all the QB2009 updates. Should I buy a new copy of QB?

      1. Hi Joshua,

        There is no need to buy the new copy of QB. Just download the final webpatch and let it update QuickBooks. It is very hard to find the program that can update it. ​


    7. I am using QuickBooks 2015 US edition and when I am trying to access company’s file then getting an error. I cannot use any unsecure tool to repair my files. Is there any guarantee that your tool will repair my files safely?

      1. Hi Dean,

        Our QuickBooks repair tool repairs the file and maintains it’s security. It does not modify the original file so your data become safe and secure.

        PS: Make a copy of corrupt file and perform repairing operation on the copied file.

        Good Luck!

    8. For me Verify Data utility is the best tool to check the corruption in the QuickBooks data file. It enables me to found any corruption issues in my data file. And the best part is it recommends Rebuilt Data utility to fix the corruption if it finds any corruption issues.

    9. Greetings,

      Informative blog about QuickBooks file repair. I am using the USA edition. Yes the file size and chances of corruption are directly proportional to each other. So always maintain the file size.
