I am a cpa and I get back up files from my clients so I can do year end adjustments and prepare their tax return. I have every version of QBooks so I'm compatible with everyone. I just tried to restore a file from a client that has been on QB2012 for a long time and the message was "The company file that you are trying toopen was created with a newer version of QuickBooks. Please upgrade your copy of Quickbooks. Would have been nice to tell me which version it is because if I just put it on 2019 and they are using 2017, then they can't restore. How do I tell which version it is? I tried right clicking on the file and selecting Properties but it's not there.
Of course, I've texted the client and I thought about trying each version, very time consuming, but I really wondered if there isn't a way to find the version that has been backed up on the flash drive, I've wondered this for a long time. Thanks for taking the time to respond.
There's no way to tell the version of a backup or a QBW file except to try to open it. Intuit did deliver a utility with older versions of QB to solve this need, but it didn't work with newer windows and they abandoned it instead of making it work.
