Hi Rav We have the "company file running very slow" problem also. We are running Accounts Hosted multi user on Windows 10. My colleague uses Google Chrome and I use Internet Explorer. I have found your ID: 3793 file on "How to Improve the Performance of your QBI company file"...but I am stuck on step number 1 ! We don't seem to have a .qbw file let alone a .qbw.tlg file in the Q drive. Please help.
