Forms Moving file location of document uploaded and connecting workbooks to sync responses

I have a Microsoft form i made to enter all of our vehicle maintenance and parts into to track it by vehicle as we have 11 vehicles. I Have a upload button on the bottom of form so I can upload from our Dropbox to save all the receipts/invoices/photos of parts to with each entry on the spreadsheet.

I need to adjust some of my folders (sub folder) where the files live on Dropbox. will doing this break the uploaded document or will it still be able to be viewed from the excel spreadsheet that is downloaded from Microsoft forms

Second Question: I need to auto populate the form responses from the workbook it syncs to that saves on our SharePoint through our office 365 subscription and have it linked to the Vehicle Tracking Workbook that lives in Dropbox in our vehicle file so when the workbook is opened on Dropbox the form responses added in via Microsoft form copies the new entries to the historical page on the Dropbox version. How can i easily sync the two workbooks together
