Thanks for your response. I gave myself a day off from the frustrations of Dropbox which I am finding very hard to use. I tried to delete a file called Pictures, which now doesn't appear anywhere in Dropbox, but in Recents it kept showing individual files from within that Pictures folder, and those individual folders I think I have now deleted, as my used storage figure has reduced a bit. I'm sure there are many more pictures left that are taking up a lot of storage, and I can't find them to have another go at deleting them. Why does it have to be so difficult?
