I can share some insights regarding your file size concern, @Carol602.

Yes, you are correct. The size of your company's data file has no actual limits. However, speed may be affected if your network cannot handle massive data files. Performance in QuickBooks suffers as the corporate file size grows.

When you have a large file and QuickBooks' performance is slow, you can reduce the size of your 303000 MB company file. To know more options in reducing the size of your file and guide you in resolving performance issues in QBDT, please see this article: Resolve QuickBooks Desktop performance issues: Manage your data file.

We can also use the Condense Data utility. This helps streamline your company data file.

Here are some valid reasons to Condense:

• You have a large data file.
• You are nearing a list limit.
• You have upgraded all your hardware.
• Your accountant and your technical support have discussed other options and are willing to proceed with Condensing.

Follow the steps below on how run Condense Data Utility:

1. Click the File menu.

2. Select Utilities and choose Condense Data.

3. Click the first radio button as shown below. Take note that the system will advise you of the approximate reduction in your file.
