Can no longer open company file on mapped network drive

I'll provide the steps on how you can fix your company file in QuickBooks, @Patrick11_2.

Before that, can you share with us if you're seeing any specific error messages or warnings about the issue? This way, I can provide you the appropriate steps to rectify this.

If you're not getting any error message, then we can proceed to the following steps to open your company files.

First, let's make sure you're using the correct file extension. Since there are a lot of file types in QuickBooks Desktop, it could be possible that your file extension is incorrect. For you to open your company file (QBW), it should be with a .qbw extension at the end of the filename.

You can also follow these steps to trace what's causing this issue:

1. Open the Windows Start menu.

2. Type “File Explorer” into the search and open File Explorer.

3. Search for and find the QuickBooks.exe file. It’s usually in your QuickBooks folder.

4. Hold down CTRL on your keyboard and double-click QuickBooks.exe. Don’t let go of CTRL until QuickBooks opens.

Once done, open your company file to check if it works. If not, try using a Sample File. This way, we'll able to point out if the issuing steam within the program. You can fix this by following the steps in this link: How to fix QuickBooks if it doesn't open.

If the sample file opens normally, you can proceed to the succeeding steps on how to fix general problems when your company file won't open.

Additionally, if you see a specific error message like this "Cannot communicate with the company file due to a firewall", don't worry. This usually means your network firewall is interrupting the connection. Just follow the steps provided in the article to fix this: How to fix "Error: Cannot communicate with the company file due to firewall".

I've also added this link about access permissions to share company files. This is to check if your manager can penetrate the folder: Set up folder and Windows access permissions to share company files.
