Agreed with Steve that steps will be as follows:

• Create a maxFileSize property on the node that is driven by the RED.settings max file size for socketIO, with the default size if no override is presented. - this this post for more context
• This will be enforced client-side to ensure SocketIO connection isn't broken
• As a follow-on task, we will then look into chunking Websocket traffic for the file transfer, which would enable better progress reporting client-side, and enable larger files to be transferred

Joe, it kinda looks like multiple upload was disabled (through the code) but the option appears to still be visible and is mentioned in the help.

can you clarify please?

@Steve-Mcl have fixed/implemented the multiple file upload, and updated docs to reflect the detail that it'll send multiple msg events
