[SOLVED] How remove fileshare from FILES?

[kormi]

I have mapped a folder from my computer on the system, but then I realized I did it wrong, the folder doesn't includes movies only, but also lots of other stuff. That creates some confusion on Xbian. I decided to do it all over again, but cannot find a way to unshare/unmap the first folder... How do I do that? Is there a way? Thanks for help...
