How can I share files over a Windows network?

I have a media computer which I recently reformatted to Ubuntu 10.04. I am probably just missing something obvious but I can't figure out how to share folders and files, so that I can browse to them on my Windows computers in order to copy files to/from the computer.

How do I do this?

Right-click a folder and select "Sharing Options". Then check off "Share this folder".

You've to right-click folder, Sharing Options, check Share this folder and mark the two options related with guest-acess and allowing of file management operations. Then click Create Share

In Windows, just go to Start Menu > Network > YourUbuntuComputer > YourSharedFolder. If your Ubuntu computer isn't showing there, try Super Key (or Windows Key) + R, and write \\ComputerInternalIP or \\YourComputerHostname.
