When I try to open any html file in dreamweaver CC I get an "Unexpected file format." error. This has never, ever happened before and this error appeared after CC updated this morning 4/18/2022. I cannot find documentation in Adobe for this error.

Also make sure your local site files reside on your primary computer drive, not cloud drives or zipped folders.

Nancy,

I uninstalled Dreamweaver CC and when it asks you to keep your preferences or not, you definitely need to say no. Now Dreamweaver CC is working. But, I had to re-install my store and other stuff. Thanks for the help.

Sometimes updates & 3rd party extensions cause the Preferences file to become corrupted. In a decade or more, I've only had to restore preferences a few times. It's not usually needed.
