Set up a network share on the PC (right-click on the folder you want to put them in and look for the “Sharing and Security” settings), attach to it on the Mac (Cmd-K in Finder if it doesn’t show up automatically), and copy-and-paste like you would normally.
Edit for bonus much faster method: If the PC has firewire, you can run a cable between them, boot the Mac in target disk mode (hold down T while booting, I think), and use something like HFSExplorer on the PC to access the Mac’s drive. Or use that with the external drive, if it’s already formatted as HFS.
I have an ftp server with stuff that I’d like to sync automatically to multiple machines. Is there a whizbang tool that does this automagically?
Ideally I’d like it to be like Dropbox, but going to my server instead of theirs (occasionally I might want to pop a 4gig file there or something). I know about rsync and scripting that, but I’d like something a bit less fiddly and more braindead.
