SP 2013 Administration - Cannot Edit Web.Config

Hello Community!

I am working in SP 2013 Enterprise and I need to edit a web.config file in order to modify the BlobCache settings.  here's the problem, when I right click on the web.config file and choose "Open With" I get this error - "Windows can't open this type of file (.config)".   has anyone else seen this problem and if so how did you resolve it?

Thanks!

Tom
