I'm delighted to have you here in the Intuit Community, @Bbach.

In QuickBooks Desktop, you can reduce your file size by using the Condense Data utility. This process still keeps your data and minimize the risk of data damage.

Please keep in mind condensing data in your account is irreversible.

Here are the steps you can follow:

1. In your account, go to the File menu, select Utilities, then Condense Data.
2. Select the best option on how you want to condense your file, then click Next.
3. Choose what transactions you want to remove, then click Next.
4. Click Begin Condense.

To learn more about this process, feel free to read through this article: Use the Condense Data utility.

You can now shrink your company file.
