More options when moving or copying files to Dropbox

I find it highly annoying, when duplicating or moves multiple files from one folder to another, when I mistakenly or unknowingly move a file that already an exists in the destination folder, and I get a message saying this to be the case and the other files dont get moved. I often move fifteen to twenty files at a time. As I have over three thousand book files, I often don't keep track of what already exists in a folder. Now when uploading multiple files, if a file already exists in the destination folder, one is given the option to overwrite the file or just upload the other files not in the folder. Please make it the same for when one is duplicating or moving multiple files to folders within Dropbox, you have no idea how annoying this is as I have to go through the files in the destination folder, make a note of the file already exsisting and then go back and reselect the files that I want to duplicate or move. Please change this!!!

Thank you.
