12 Solutions for Common QuickBooks Company File Errors

When you first begin using QuickBooks, you create your company profile. Along with this profile, QuickBooks also creates a corresponding company file. 

Over months and years of use, your data associated with this company file will grow along with the volume of data used.

QuickBooks company file errors will occur, so we created this guide to help you understand the ins and outs of company file errors, along with some valuable tips to save you any frustration.

If you run into QuickBooks errors you can’t figure out on your own, don’t panic! That’s why our experts are here to help.

What Is the QuickBooks Company File?

The QuickBooks company file is a file stored on your computer where QuickBooks Desktop saves your company’s financial data. This file contains all the data on your day-to-day transactions, accounts, and contacts.

The company file is unique for each company profile you create in QuickBooks. So, if you create multiple company profiles inside QuickBooks, each profile has a company file.

Before Troubleshooting

Before trying to resolve any QuickBooks errors, begin by doing the following:

  • Create a backup of your QuickBooks company file.
  • Update your QuickBooks to the current version.

Identifying the QuickBooks Company File Location

If you need to find your QuickBooks company file(s), you are looking for two specific file types:

1. .qbw

This is your QuickBooks working file.

2. .qbb

This is your QuickBooks company file backup file.

To locate these files, do the following:

  • Open your instance of QuickBooks.
  • Navigate to the “No Company Open” window inside QuickBooks.
  • Click “Find a Company File”.

This will bring up any QuickBooks working company files that exist on your computer.

Alternatively, you can find these files without having QuickBooks open. This is useful, especially if you get an error when opening QuickBooks. 

  • Go to your computer’s Start menu.
  • Select “My Computer”.
  • Search for “File Explorer” and open it.
  • Search for a specific file, or specify “.qbw”.

To narrow this search, you can try looking specifically in the location where QuickBooks installs these files. This is typically located on your “C” drive: C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files.

QuickBooks Crashes When Opening the Company File

If QuickBooks crashes when you first go to open it, the following are several things you can try to resolve the issue.


Don’t Save the QuickBooks Desktop

You may have too many windows open in QuickBooks, so when you re-open QuickBooks, it doesn’t have enough resources to open. Press and hold the ALT key while you open your company. If this resolves the issue, you can also go to QuickBooks’ preferences tab and choose “don’t save the desktop,” and this should prevent the issue from recurring. 

Turn Off Hosting

If you are hosting your QuickBooks company file in a network, try turning off “Host Multi-User Access” on your workstations.

Open a Sample Company File

One of the things you are trying to figure out is whether your error is happening because of a problem with the QuickBooks program or your company file. To diagnose the issue:

  • Open the Windows Start menu.
  • Press and hold CTRL.
  • Select QuickBooks.
  • When QuickBooks is open, select Open a Sample file.

If QuickBooks won’t open, you now know that the problem is with the program, and you can contact an expert to get assistance.
