Yes, Ive found Forum Customer Support answers to never be complete or addressing the exact issue. It's all to push you to pay for there additional customer support to get the simpliest answer possible!

I also have the same issue where my "working files" (QBW) are saving to a completely different drive then the backups (QBB). I can direct where to save the backups but when I open the company working files, they pull from the working file saved to a different drive- I believe this is the reason my data file is constantly broken and needign rebuilding- But it's impossible to find any answers through forums alone!

I want to move all my working file (QBW) to the same drive as the QBB backups, but I'm concerned over QB not finding the files when I try to open them again bc QB does not actually allow me to choose where I pull the working fines from- it's currently auto saving my working files to ONEDRIVE!!! 

I paid for customer support for one year and it cost over $700! It expired as soon as I actually needed to support and I wasn't about to pay again for it.

These forum answers are just typical "almost there" answers that leave you frustrated and without resolve to force you to give into paying for their support!
