So if I understand you correctly, (again, moving everything to a different PC) I don't need to backup the client companies? I can just copy the *.qbw files to say a thumb drive; then paste them to the new directory structure on the new PC?
And then "Open or restore an existing company" and QB won't balk about its location being different?
And she does payroll for most clients. And all I need to do here is copy the Tax Forms folder over to the same new directory?
Yes, you can just copy the .qbw files and paste them to the new directory structure. However, I suggest you secure a backup of your company file to safeguard your data in case restoring won't be successful.
