Redframe’s File Transfer only lets you upload a single file at a time per transfer.

To send multiple files in a single file transfer, you can compress multiple files into a single ZIP file and then upload that ZIP file. Your clients will then be able to unpack the ZIP file on their computer and access the multiple files within.
