Does anyone know if sending files between computers over the same Wi-Fi connection uses your telco's bandwidth?

I recently set up a homegroup network on windows 8.1 to connect the laptop and PC together and found i can stream music/movies from my PC through to my laptop. But i dont want to do this if it is going to chew up my little data plan.

Anyone with previous knowledge, personal experience ?

Nope, if it doesn't leave your network then it doesn't use your ISP data.

If you want to test this to see if I'm telling the truth, unplug your ADSL / VDSL line from your modem but leave the modem on. If you can still transfer data then it's not leaving your network and you are not using your ISP data.

Not normally. Your router or modem-router ensures that your communications only go to the intended device(s).

Your router or modem/router creates a Local Area Network (LAN) which each computer can join using an ethernet cable or a wireless connection. Your router normally assigns local IP addresses for each connected device too. When it receives a message from device A for device B, it routes it to the correct device. So your streamed music is not broadcast to every connected device including your Internet connection. In other words, any communication on the LAN does not need to go out through your ISP's Wide-Area Network (WAN) connection.

This short article with picture might help you to visualise it.

But if you are using Dropbox or another cloud file sharing service to move the data between computers then it most likely will use your ISP data.

Nope, the dropbox will get the files from within the local network first.

I have a NAS that is connected to my dropbox account, I setup my new desktop, the dropbox will sync the files from my NAS via local network first.
