I thought I'd found the solution in the community until discovered that Dropbox is not in my system and I can't uninstall it. I was running out of space on my notebook and needed to rationalise, so used DB online on my notebook instead. Now all the files are out of date I need to delete them from the notebook, leaving them intact on my desktops and online but Delete shows the error and I can't untinstall. Any ideas please?
