The Properties File Configuration Editor appears in the Results pane.
The editor displays the grid where the name and value of each property is entered.
This is the name of the pseudo-variable that is created when the region is started.
You can use pseudo-variables that define path fragments as part of a location definition, for example:
$MYVAR/subdir, c:\mydir\$MYVAR, c:\mydir\$MYVAR\subdir
The properties file and the locations it defines are available for use with your region startup files.
