On the new operating systems for MAC, you cant see file sizes on files or folders that are set to online only. In past MAC operating systems, this function was so helpful to see the file sizes. Now once you download files from desktop app and re-save them as online only, file size says zero. This completely makes the desktop app complete useless. As a business owner, we deal with files that are huge 100g or larger and always check to see if we copy or move files that the files copied or moved successfully. We always check the file size to validate our online movements. By deleting this function makes the desktop completely useless and needs to be immediately re-instated. If your file or folder has a cloud icon next to it, everyone knows its online and not taking up any local hard drive space. To have it set to zero people like myself thinks the file was deleted. Extremely poor management and planning on dropbox part, not much thought went in while changing this process..
