(Some browsers just start saving right away to a Downloads folder on your computer.) To work around this, you can go up one level in the folder directory and come back, or close that tab in your browser and navigate to the folder again.If your browser prompts you, choose Save or Save As and browse to the location where you want to save the download. The Download button may sometimes disappear if you refresh the web page while looking at a folder.
The Download button will only appear when files or folders are selected.
