Normally, the tree only displays the Project File and the Data Files under it. You can also have the program display the individual Surveys inside the data files. To do this, simply click on the "Show Surveys" check box below the tree. The program will then scan through all the data files and show the individual survey names. (If the cave is large, it may take several seconds to scan through the file.) If the Data Files cannot be located, no surveys will be displayed. (Note: if the tree is not expanded, you may not be able to see the individual surveys. Just click on the Expand Button to see the surveys.)
