I use Google Drive and Dropbox for completely different things and very rarely move or copy a file from one to the other. When I do, it is a simple 'drag' in Windows File Explorer. I have not set up any kind of major move between them so I do not understand my having received a Notification of "Migration of Google files will begin in 5 days". Can anyone explain what it means or why I received this ?
I have concerns that someone ELSE may be in the process of a wholesale move of my files, but have no idea who might be doing that. I suspect I would not receive this if it were someone with whom I've shared folders copying them to Drive (which would be dumb). Should I interpret that someone has indeed hacked my Dropbox account ?
