Sorry, I'm sure this has been answered on here many times. I don't even know where to begin to look for this answer w/out leaving more confused.

I have dell inspiron e1505. It has win xp on it. I just upgraded to a mac. But still use both of them. There are many options to setup networks and differ things etc. on my dell but I can't seem to get any of them to work, way too confusing.

Anyways to my actual topic-

I want to have a folder on my dell where I can put files in. Then, with my Mac, log into the folder and and copy the folders from the dell's folder onto my Mac hard drive. Thats basically it, I don't want to stream music or anything like that from it, unless that's just as easy to do.
-I want to do this wirelessely.
-I have comcast broadband in my apt. It's hooked up into my roommates computer and he has a wireless transmitter, so I just log onto the internet via wireless.
- can this be done wirelessly? Both computers are wireless, and both log into the same wireless account.
-Any help would be appreciated, If you need any more info just let me know.
