Thanks for joining the thread, @yuriko.
I hope you're having a beautiful day. Allow me to provide some insight into combining two separate company files.
When you have two company files on two separate computers, QuickBooks Desktop will recognize each file but won't allow you to combine the two into one. However, if you need to blend the information in these two files, I recommend checking out the QuickBooks app center. The website has over 600 third party applications that you can search through to find an app that allows you to combine both company files into one. You can ask other Community members for their suggestions as well.
