need help transferring files to another computer, win xp

Hello I am so confused how to do this I hope someone can take me through step by step.

I have two notebook computers that both connect to the same wireless modem/router. I am trying to take some files from notebook A and trying to transfer them to notebook B through the wireless connection, both computers are using win xp.

I will really appreciate the help,

First step is to run the network setup wizard on both machines and have them both on the same workgroup. I'd recommend you change the workgroup to something other than the Microsoft default of MSHOME. Just be sure both computers are on the same workgroup.

Then, set up sharing. This can be done on either a drive level (share the entire drive) or on a folder level. I recommend folder level. Right click on the folder you want to share and select "sharing" from the menu. Follow the instructions.

Yes, use that one.

Yes, you run it on both computers.

You will want to disable the firewall in your computers until this setup is complete, but not in the router. You also do not need to disable the WEP, but you will need to know the key when you set up each of your computers.
