Find any file of *.QBW, *.QBM, or *.QBB

Thanks. Those are always the files I look for, but those seem to be dated 2/11/2020 so are not of any help for the last several weeks that I had data entered for.

Those are always the files I search for, but for whatever reason, they are all back dated to 2/11/20 even though I had entered data through 3/15.

 

I'm working currently with Quickbooks 2017. I had to restart my computer on Friday, and when I reopened it, it appears to have lost my file for the past month (last file has invoices only until 2/11/2020. I can locate an .sdu file that appears to be more recent, but I am unfamiliar with that file type and it also won't open.

Hi there, tranquiljourney.

 

I'll help you in locating your company file.

 

In QuickBooks version 2017 .SDU files are used to store apps, access rights and login details for QBW files. Generally, these files are stored in one location, which is C:\Users\<username>\Intuit\QuickBooks\<hash based subfolder name>\<qbw file name>.sdu.

 

The location of our company file depends on where it was originally stored. We can open the Product Information page to trace the .QBW file by pressing F2 on your keyboard. 

 

We can also check your backup settings to locate the directory or folder location of the backup file. I'll guide you how:

 

  1. Select File from the top menu bar.
  2. Choose Back Up Company
  3. Select Create Local Backup
  4. Click the Options button.
  5. Check the folder location under Tell us where to save your backup copies.

If you're still unable to find it, we'll have to conduct a wildcard search on your computer. We can type one of these following extensions in the search bar of the Start Menu. Please make sure to include the asterisk (*) before the file type.

 

  • *.qbw (Working Files)
  • *.qbb (Back Up Files)
  • *.qba (Accountants Copy Files)
  • *.qbx (Accountants Transfer Files)
  • *.qby (Accountants Change Files)

For more details about this process, you can refer to this article: Company file is missing or cannot be found. It also contains information about the things you need to do once the file is found.

 

Let me know how it goes in the comment section. I want to make sure you can successfully locate your company file.

Unfortunately, I already tried those methods. The only qbb/qbw files are dated 2/11/20; only the .sdu file is dated more recent (3/13/20), but I can't access it.

I appreciate the troubleshooting steps you've performed, tranquiljourney.

 

QuickBooks has a feature that can recover missing data using QuickBooks Auto Data Recovery. This helps you get back your lost file by:

  • restoring transactions using your current Transaction Log file and copy your Company file.
  • restoring a few hours of transactions with a copy of both the Transaction Log file and your Company file.

Here's an article that will guide you through the step by step process: Recover lost data with QuickBooks Auto Data Recovery.

My QBW file has been changed to an SDU file.  I need to convert it back and don't understand how this happened!

Thanks for joining this thread, @EKOHL.

 

It seems that your file might be corrupt or in an unexpected format. Since SDU file type isn't part of the supported file type in QuickBooks, let's rename the file extensions to .qbw. 

 

Make sure to include the asterisk (*) before the extension type (like *.qbw, *.jpeg, *.xls, *.js, *.docs, *.png) to ensure the search works correctly. Here are the other supported file types in QuickBooks:

 

  • *.qbw (Working Files)
  • *.qbb (Back Up Files)
  • *.qba (Accountants Copy Files)
  • *.qbx (Accountants Transfer Files)
  • *.qby (Accountants Change Files)

 

Also, I'd suggest reaching out to an IT expert. They can provide other troubleshooting steps that can help you fix it.

 

I'm adding this article for more details about the use of different types of files to store different types of data: File extensions used in QuickBooks Desktop.

I am having the same problem  Were you able to fix it.? My company file was replaced with the SDU extension which I can't seem to access.   Searches on *qbw, etc extensions don't find it either.  Only a sample file and the sdu file.  It was fine last week.  Now it can't be found.

Thanks for checking this with us, BSJ.

 

QuickBooks Desktop (QBDT) doesn't support SDU file types. In this case, you'll need to get in touch with an IT professional to help you access the SDU extension of your file.

 

Might also want to check out this article about the different file types and extensions support by QBDT: File types and extensions used by QuickBooks Desktop

 

If you need other helpful articles in the future, you can always visit our site: Help articles for QuickBooks Desktop.

 

Let me know if there's anything I can help you with. Have a great day ahead.

I too had this problem.  I tried everything including OB support and IT service.  They know nothing about it, I had a backup of two weeks before and had to recreate all the work I had done since then after restoring it.  No idea what caused it or how to fix it.  It seems to be related to QB 2017 but not real sure.  A lot of time was lost and causes bad feelings toward QB!  I do hope you have a more current backup and don't lose time and money seeking a fix.

Did you find any ADR files?

Thank you for your response.  Unfortunately, my latest backup is 9/2020.  I use QB only a few times a year for a small company (since 2010).  Fortunately I did their taxes before this mess.  Definitely a problem QB should address.

Hello there, BSJ.

 

QuickBooks have the Auto Data Recovery (ADR) feature that keeps your data in case it's corrupted or lost. It is only available in QuickBooks Pro, Premier, and Enterprise Solutions for windows. You can check out this link for more details: Recover lost data with QuickBooks Auto Data Recovery.

 

Our Phone Support Team can also help you recover data loss and can perform advanced troubleshooting steps remotely. 

 

Let me know if you have other questions. The Community is always ready to help. Take care!

Auto Recovery was the first thing i tried.  It did not work for this problem.
