I am trying to simply make a copy of the complete contents of my Dropbox folder by option-dragging it to another location on my Mac (not using File Provider). However, I keep getting “operation not supported” messages, the number files remaining jumps all over the place from negative numbers, zero, etc, and the copy operation keeps failing. Is this due to the fact that “online only” files are not there to be copied initially? Is there no way to turn off online only files and make all files available offline? It turns out to be quite difficult to take everything out of a Dropbox, doesn’t it.
