I'm delighted to answer your concern, @AvonDM.

In QuickBooks Desktop, you have the option to reduce your file size by using the Condense Data utility. Please know that condensing data in your account is irreversible.

Here's how:

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

You may also want to convert your data from QuickBooks Desktop to the Online version. Here's the link for your future reference: Move your QuickBooks Desktop file to QuickBooks Online.

Get back to me if you have additional concerns. I'll be there to help you again.
