transfer big files from mac to windows

Hello,

I recently bougt a new Windows PC for video-editing.

I have around 80GB's of video files on my mac and I want to transfer them to my new Windows PC. I Have a Lacie (external flash drive?) of 250GB that I want to use to do that. The problem is that USB's can only work with Windows and Mac if they are FAT formatted, and FAT formatted USB's have a maximum of 4GB's. So doing it that way would take forever.

I also tried to transfer my files over wifi, but my internet connection has a maxium of 300kb per second, so that would take forever too.

So in short:

Is there any possibility to transfer my files from a mac to a windows PC?

I realy hope someone can offer a solution...

Thanks,

Julius
