I actually like using FTP more.
IE makes it easy (amazingly).
Turn on FTP in System Preferences->Sharing
Get on your PC, type into any address bar (or open IE and type this there):
Code:
ftp://[your short user name on your mac]@[your mac's IP]/
It'll ask for your password, and BAM! You're in, done, and it keeps it away from the windows OS as much as possible (by keeping it in the FTP client).. so if there are connectivity problems, YOU WILL NOT CRASH WINDOWS.
Bookmark it and/or save the PW if you want, works great, only access to your user folder (even if you're admin), no access to your drives (unless you do a soft link through the terminal to something). Create a user if you'd like..
Oh man so much better than using all of that other silliness.
