Network Hub -- duplicates ALL traffic to ALL devices ?

Everyone has always said HUBs are bad and send information to ALL devices

I have an employee that needs another PC setup next to them ASAP and I do not have time to run another 100' CAT6 cable from the switch to this PC, therefore I just setup a small $10 cheap hub as follows

 1. patch cord from SWITCH to HUB
 2. patch cord from HUB to PC #1
 3. patch cord from HUB to PC #2

Which one of the below options will happens since a HUB is now in the mix when PC #2 updates a file on the Windows 2012 R2 file server since I did not wire back to the Cisco switch ?

    ** Option #1 = PC #2 sends info to ALL 100+ devices on my network, with only the file server accepting the data

    ** Option #2 = PC #2 sends info to ALL devices that are plugged into the hub (i.e. only PC #1 and the switch), with only the file server accepting the data

   ** Option #3 = something else ?

Replace that cheap hub with a cheap switch.  I didn't know they even still made hubs.

Ok, but just for my knowledge, which of the above options will happen currently until I get a cheap switch ?

If the Hub is old enough it may need crossover cables or it may not even work in a modern environment. I would replace it with a small switch as stated (Best Buy, some hardware outlets). You can pick one up in an hour or so.
Your help has saved me hundreds of hours of internet surfing.

I believe Option #1 would be the case, but again, it's been forever since I've used a hub.  I've pretty much forgotten all the nuances of them.

I think this would happen because the hub has no routing capabilities.

>there's really no need to have a hub around.

Hubs are nice if you have switches that don't do port mirroring when doing packet captures.
