Thank you for your response.

the shared drive location is not avail.  i can still backup at my document or flashdrive so i dont think its data issue but it seems like QB does not give me an option to store shared drive.

only way i can store the same location is backup at mydocument (on my pc) or flashdrive first and move to Shared drive.  so this means share drive has enough space to store this.

simply QB removed the option to store the shared drive where it was stored before.  see pic attached.

also when i extracted report in excel, excel option is grey out but only CSV format.
