If you have a wireless network but no fileserver, this is a nifty piece of software that will allow you to share files over http with a minimum of effort.

File Server is a simple http file server that can run on local computer systems. The program is a command line tool without graphical user interface. A user wanting to share files need to manually edit the FileServer.conf file with a text editor to add the right root directory and port for the file server.

The IP and port of the file server can then be shared with users who are allowed to access the file server. All that these users need to do is to point their web browser to the IP and port.

Course you could use the Apache binary as well, if you wanted to get much more fancy...
