Currently, ComfyUI does not support direct uploading and downloading of entire folders through the user interface. You can upload and download individual files, such as custom nodes, but if you need to handle entire folders, you'll have to compress them into a ZIP file for uploading and decompress them after downloading. This workaround allows you to manage multiple files at once, albeit not as directly as handling folders. If you need further assistance with this process, feel free to ask!
