Reject files that don't fit a scheme

[FreshImmuc]

how do i reject file uploads at all?

That would be up to you - but you can throw an error and pass back the rejected signal; here is an example from the default STOR command:

ftp-srv/src/commands/registration/stor.js

Lines 61 to 65 in 50e8c45

	.catch((err) => {
	log.error(err);
	this.emit('STOR', err);
	return this.reply(550, err.message);
	})
