I cannot open my company file.  I just get an error message stating the company file cannot be opened.

It is not a password issue.  I am already in quickbooks and wanted to open company information and it will not open.  It says it cannot open with a yellow triangle but doesn't say why it can't be open.

Hello there, @KJT11. 

I'm here to help you open your company file successfully. Also, I appreciate you including extra information.

We have a few solutions to fix a company file that won't open. Solution 1 is to update QuickBooks and check the file type.

1. Update QuickBooks Desktop to the latest release.
2. Make sure the file you want to open is a company file (.QBW). You can't open other file types, like backups (QBB) and portable files (QBM), the same way.
3. Make sure your file isn't compressed or encrypted:
   • Right-click the company file and select Properties.
   • Select Advanced.
   • Clear the Compress and Encrypt checkboxes.
   • Select OK.

If it's showing the same outcome, we have another set of steps to follow. Open your company file without saved windows. Here's how:

1. Open QuickBooks Desktop.
2. In No Company Open, select your company file. 
3. Press and hold ALT on your keyboard and then select Open. Don’t let go of ALT until the file opens. If QuickBooks asks you to sign in, release ALT and enter your password. Press and hold ALT again and select OK.
4. If your company opens successfully, turn off the Save the desktop when closing preference. Go to Edit and select Preferences.
5. Select Desktop View.
6. Select Don't save the desktop and then OK.
7. Close and open QuickBooks again and open your company file.
