I updated to Visual Studio 2017, and now my project directories are being cluttered with .bak files corresponding to files I modify. For example, if I edit a file named LintLicker.cs, the next day when I load my project, I'll notice LintLicker.cs.bak.
I can't find an option setting that controls whether or where .bak files get created. How can I stop this clutter--preferably by changing the location where backup files get created, but if necessary just preventing VS from creating them?
