Windows .BAK files

I don’t know if this is a Cubase 8 issue or Windows 7, but recently I have started to get a lot of backup .BAK files written regularly to project folders. I understand what they are, but I don’t want them, as I regularly back up to a separate disc. Windows Backup has not been set up.

How do I disable this writing of BAK files?

These are not windows files, they are the Cubase autosave backup project files.

You can change the settings in preferences/general if you’re certain you don’t want them.
Personally I would never turn them off completely.

Ah, OK thanks.

I see on checking Preferences that you can change the regularity of the backups and also limit the total number, so on that basis it’s fine.
