There are some special functions in FitNesse that require you to name a directory path. You do this with the !path directive.

Markup Text
Displays as
!path c:\directory classpath: c:\directory

You can also specify all the .jar files in a directory by using a wildcard:
!path /usr/javalib/*.jar


Or you can specify all .jar files in a directory and all subdirectories by using the ** wildcard.
!path /usr/javalib/**.jar


Paths such as these will be used when you press the test or suite buttons on a page.
