Answer 2

Rei As others have answered... yes... Socket.io supports the ability to transfer files.
Whether it's a good idea or not will depend on your specific use case, expected frequency of uploads, expected size of files, whether or not you're supporting mobile devices as clients, etc.
For simple scenarios involving periodic upload of small files, the implementation is rather straight forward.
However, in cases, where you'll need to upload larger files, you'll want to use a NodeJS middleware called Multer for multipart/form-data support to send chunks of your file at a time.
I'm including a few links I've vetted that should help you figure this out.
