Enviro
The Data Path
	- If you want to put your Data directory in another location, or in several 
	different locations on your machine, then you should edit your Data Path.
- The easiest way to do this is to use the Terrain 
	Manager Dialog.
The vtp.xml file
	- Alternately, you can edit your vtp.xml file.  This file 
	is created (if it does not exist) the first time you run Enviro.
 It is located in your settings folder.
 On Windows, this is typically C:\Documents and Settings\User\Application 
	Data
 On Windows >= 7, it may be in C:\Users\User\AppData\Roaming
 On Unix, it is typically your account's home folder.
- If you have data in multiple places, you can simply put more than one "DataPath" 
	element into thevtp.xmlfile, and all the data on all the paths 
	will be available to all the VTP applications.
- A path can be relative or absolute, and should leave on a trailing slash.  
	For example, the default path is:
     <DataPath>../Data/</DataPath> 
 You could add paths such as these, depending on your platform:
     <DataPath>../../Data/</DataPath>
 <DataPath>C:\MyData\</DataPath>
 <DataPath>/home/me/mydata/</DataPath>
