In my backup folder I have all the QBB files, but also have MANY QBW files. Am I correct in thinking the QBW are working files and the QBB are the Backup files? With the QBW files I also have DSN, ND and LGB files which have the same date as the QBB File. Do I  really need any of those files as long as I have the QBB File? 

If I do need to save those should I put them in folders based on Date? My guess is I no longer need those and saving ONLY the QBB files is the way to go? 

Any help appreciated. Oh BTW I am running Quickbooks 2024. Thanks
