How to split / archive a corrupted .dbs file (or) create a new company file from the old one?

Thank you for reaching out to the Community Duraflex! I will be happy to help you create a new company file from the existing one. Here's how:

1. Open QuickBooks Desktop and the company file you want to copy.
2. Find where you saved your file by pressing F2 to open the Product Information window.
3. In File Information, see where you save your company file on your computer.
4. Back up your company file and rename it when you restore your company file.
   Note: This creates a unique copy of your original company file.  Save the new file to a unique folder.

From there, you would need to remove transactions from the copied company file, check your accounts, and add any other online banking. No worries though, this article below has step by step instructions:

• Create new company files from existing ones in QuickBooks Desktop

Thank you for the reply. This process would copy over all 5k+ potentially corrupted negative inventory records/transactions. We have no idea what those records/transactions are or where to even start looking for them. Is there a way to search for all negative inventory transactions?

You need to run the Condense Data utility to remove old data and create a new company file with a condensed one. The problem is you will need to fix the Negative Inventory issue beforehand.

Run the Inventory Valuation Detail (IVD) report and select Reports>Inventory>Inventory Valuation Detail.

Click the Dates drop-down and select All.
Find all occurrence's of negative amounts in the On Hand column.

Scroll through the report to an item that is showing a negative amount in the On Hand column.
If you can do so legitimately, adjust the dates of the bills and/or invoices so that the bill dates are before the invoice dates.

Repeat those seps for each item with a negative quantity in the On Hand column. It is not sufficient to adjust the current QOH to a positive value. You must eliminate each occurrence of negative QOH.

If you don't have time to fix them, you can purchase a 3rd party service to do so during weekend to lower your downtime.
